Title: Tidal Disruption Events: Observational signatures of quiescent black holes


Speaker: Ashley Zauderer, Harvard


Host: Raffaella Margutti

Abstract: I will present a brief overview of theoretical predictions for observational signatures of the tidal disruption of stars by supermassive black holes. In 2011, the Swift satellite observed a source, J1644+57, which arguably is the most clear-cut case for a tidal disruption event. This event is unique because it deviates from the simple predictions: strong radio emission was observed starting at early times, providing evidence for a collimated, mildly-relativistic jet. I will outline the utility of radio observations to monitor the expansion and energy scale of the relativistic outflow and to probe the parsec-scale environment around a supermassive black hole that may have been previously dormant. I will conclude with a summary of interpretations for this event and open theoretical questions.

Title: Structure of the photo-catalytically active surface of SrTiO³

Speaker: Joel Brock, Cornell University 

Abstract: 

A major objective of energy research is to employ light to cleave water directly, without an applied bias, into hydrogen and oxygen. Since the initial reports of the ultraviolet activity of TiO2 and SrTiO³ in the 1970’s, researchers have pursued the development of photo-active materials and a fundamental understanding of the mechanistic and molecular-level phenomena involved in photo-catalysis.[1-7] While surface science, utilizing ultrahigh vacuum (UHV) techniques to study well-defined materials (e.g., single crystals), has provided many insights, we still know relatively little about molecular-level processes near electrodes in contact with electrolytes under operating conditions. Here, we report observations of the surface-structure dependent photocatalytic activity of SrTiO³ towards the water splitting reaction under active potential control[8]. Pre-treating the electrode surface, by biasing to potentials where oxygen evolution occurs in basic medium, irreversibly reorders the surface and nearly triples the photo-induced water splitting activity at open circuit, as measured by scanning electrochemical microscopy (SECM). Using in situ X-ray reflectivity, we obtain the history-dependent structure factor along the (001) face of a SrTiO³ electrode/electrolyte interface during photoassisted electro-catalysis. First-principles joint density-functional theory (JDFT) interpretation of the X-ray data suggests a biaxially strained anatase-like structure as the active operando surface.

Title: Chemical structures in planet-forming disks

Speaker: Karin Oberg, Harvard Smithsonian 

Abstract: Exo-planets are common, and they span a large range of compositions. The origins of this compositional diversity are largely unconstrained. Among planets that are Earth-like, a second question is how often such planets form hospitable to life. A fraction of exo-planets are observed to be ‘physically habitable’, i.e. of the right temperature and bulk composition to sustain a water-based prebiotic chemistry. This does not automatically imply, however, that they are rich in the building blocks of life, in organic molecules of different sizes and kinds, i.e. that they are chemically habitable. In this talk I will argue that characterizing the chemistry of protoplanetary disks, the formation sites of planets, is key to address both the origins of planetary bulk compositions and the likelihood of finding organic matter on planets. The most direct path to constrain the chemistry in disks is to directly observe it. In the age of ALMA it is for the first time possible to image the chemistry of planet formation, to determine locations of disk snowlines, and to map the distributions of different organic molecules. Recent ALMA highlights include constraints on CO snowline locations, the discovery of spectacular chemical ring systems, and first detections of more complex organic molecules. Observations can only provide chemical snapshots, however, and even ALMA is blind to the majority of the chemistry that shapes planet formation. To interpret observations and address the full chemical complexity in disks requires models, both toy models and astrochemical simulations. These models in turn must be informed by laboratory experiments, some of which will be shown in this talk. It is thus only when we combine observational, theoretical and experimental constraints that we can hope to characterize the chemistry of disks, and further, the chemical compositions of nascent planets.

Tigran Kalaydzhyan: Testing gravity on accelerators

February 6, 2017, 4:00 PM - 5:00 PM

Title: Testing gravity on accelerators

Speaker: Tigran Kalaydzhyan, CALTECH
 

Abstract: Weak equivalence principle (WEP) is one of the cornerstones of the
modern theories of gravity, stating that the trajectory of a freely
falling test body is independent of its internal structure and
composition. Even though WEP is known to be valid for the usual
matter, it has never been experimentally confirmed for antimatter and
relativistic matter. We make an attempt to constrain possible
deviations from WEP utilizing the modern accelerator technologies. We
analyze the (absence of) vacuum Cherenkov radiation, photon decay and
anomalous synchrotron losses at the Large Electron-Positron Collider
(LEP) and at Tevatron to put limits on a difference between the
gravitational and inertial masses of the relativistic
electrons/positrons. Our main result is the 0.1% upper limit on the
mentioned difference. I will further explain how this figure can be
improved with the analysis of a high-energy Compton scattering at the
future International Linear Collider (ILC). The talk is based on the
following publications,

Title: Topological photonics: from classical to quantum

Speaker: Mohammed Hafezi, University of Maryland

Abstract: There are tremendous efforts underway to better understand systems with topological order --- global properties that are not discernible locally. The best-known examples are quantum Hall effects in electronic systems, where insensitivity to local properties manifests itself as conductance through edge states which is insensitive to defects and disorder. In this talk, I demonstrate how similar physics can be observed for photons; specifically, how various quantum Hall Hamiltonians can be simulated in an optical platform. I report on the first imaging and measurement of topological photonic edge state using silicon-on-insulator technology and our recent advance in studying the quantum transport of such topological photonic structures. Furthermore, the addition of optical nonlinearity to this system provides a platform to implement fractional quantum Hall states of photons and anyonic states that have not yet been observed. More generally, the application of these ideas can lead to the development of optical devices with topological protection for classical and quantum information processing.

Abstract: 

What is the possibility of other intelligent life in the universe? Can we detect radio, infrared, or optical signals from other civilizations? Current and future SETI projects, including the new $100-million Breakthrough Prize Foundation Listen project, may provide an answer. Berkeley SETI Research Center chief scientist Dan Werthimer will describe the rationale for past and future searches and will show how new technologies are revolutionizing SETI.

Dan will also describe the SETI@home project, which analyzes data from the world's largest radio telescope using desktop computers and cell phones from millions of volunteers. SETI@home participants have formed one of Earth's most powerful supercomputers. Volunteers have the small but captivating possibility their computer will detect the first signal from a civilization beyond Earth.

Title: Space astrometry: the Hipparcos and Gaia missions

Speaker: Michael Perryman

Abstract: 

Alone amongst the space agencies, ESA made its entry into space astrometry with the adoption of the Hipparcos mission in 1981. Outside of the astrometric community, it was viewed at the time as fundamental if not particularly exciting, although Freeman Dyson described it as "... the first time since Sputnik in 1957 that a major new development in space science has come from outside the US". In his ASP Millennium Essay in 2001, Cavendish Professor Malcolm Longair stated that "It is invidious to single out surveys which I find particularly impressive, but I make an exception for the Hipparcos astrometric satellite".

Hipparcos delivered its high-accuracy catalogue of 120,000 star distances and space motions in 1997. As a follow-up, ESA accepted the Gaia mission in 2000. Launched in 2013 and expected to operate into the next decade, Gaia will represent a revolution in its dynamical stereoscopic mapping of our Galaxy, promising a catalogue of more than a billion stars to 20 magnitude at microarcsec-level accuracy.

The talk will provide a short historical context and describe the scientific motivation for these missions, outline the essential experimental principles which underpin their measurements, and give an overview of the science objectives, including Gaia's expected yield of many thousands of astrometrically-detected exoplanets.

Massachusetts Institute of Technology
Laser Interferometer Gravitational-Wave Observatory (LIGO) Collaboration

Dr. Rainer Weiss is a preeminent physicist who for 40 years has worked toward the first direct detection of gravitational waves announced in 2016. Dr. Weiss is professor of physics emeritus at MIT and is one of the founders of LIGO, the instrument that first heard gravitational waves emit from the merging of two supermassive black holes 1.3 billion light years from Earth. Dr. Weiss developed the concept behind LIGO as an exercise for a course on general relativity that he taught at MIT in 1967. Today the LIGO Collaboration is comprised of over 1,000 scientists and engineers world-wide.
