New physical insights about Tidal Disruption Events from a comprehensive observational inventory at X-ray wavelengths
Katie Auchettl, James Guillochon, Enrico Ramirez-Ruiz
We perform a comprehensive study of the X-ray emission from 70 transient sources which have been classified as a tidal disruption event (TDE) in the literature. We explore the prop…
The Astropy Problem
Demitri Muna, Michael Alexander, Alice Allen +151
The Astropy Project (http://astropy.org) is, in its own words, "a community effort to develop a single core package for Astronomy in Python and foster interoperability between Pyth…
Simulations of Magnetic Fields in Tidally-Disrupted Stars
James Guillochon, Michael McCourt
We perform the first magnetohydrodynamical simulations of tidal disruptions of stars by supermassive black holes. We consider stars with both tangled and ordered magnetic fields, f…
OGLE16aaa - a Signature of a Hungry Super Massive Black Hole
Łukasz Wyrzykowski, M. Zieliński, Z. Kostrzewa-Rutkowska +22
We present the discovery and first three months of follow-up observations of a currently on-going unusual transient detected by the OGLE-IV survey, located in the centre of a galax…
An Open Catalog for Supernova Data
James Guillochon, Jerod Parrent, Luke Zoltan Kelley +1
We present the Open Supernova Catalog, an online collection of observations and metadata for presently 36,000+ supernovae and related candidates. The catalog is freely available on…
Prompt Radiation and Mass Outflows from the Stream-Stream Collisions of Tidal Disruption Events
Yan-Fei Jiang, James Guillochon, Abraham Loeb
Stream-stream collisions play an important role for the circularization of highly eccentric streams resulting from tidal disruption events (TDEs). We perform three dimensional radi…
