TDE Hosts are Green and Centrally Concentrated: Signatures of a Post-Merger System
Erica Hammerstein, Suvi Gezari, Sjoert van Velzen +17
We study the properties of the galaxies hosting the first 19 tidal disruption events (TDEs) detected with the Zwicky Transient Facility (ZTF) within the context of a carefully cons…
Seventeen Tidal Disruption Events from the First Half of ZTF Survey Observations: Entering a New Era of Population Studies
Sjoert van Velzen, Suvi Gezari, Erica Hammerstein +34
While tidal disruption events (TDEs) have long been heralded as laboratories for the study of quiescent black holes, the small number of known TDEs and uncertainties in their emiss…
Probing the Jet Turnover Frequency Dependence on Black Hole Mass and Mass Accretion Rate
Erica Hammerstein, Kayhan Gultekin, Ashley King
We have examined a sample of 13 sub-Eddington supermassive black holes hosted by galaxies spanning a variety of morphological classifications to further understand the empirical fu…
Constraining the inclination of the Low-Mass X-ray Binary Cen X-4
Erica K. Hammerstein, Edward M. Cackett, Mark T. Reynolds +1
We present the results of ellipsoidal light curve modeling of the low mass X-ray binary Cen X-4 in order to constrain the inclination of the system and mass of the neutron star. Ne…
