Exploring Damped Lyman- System Host Galaxies using Gamma-ray Bursts
Vicki L. Toy, Antonino Cucchiara, Sylvain Veilleux +6
We present a sample of 45 Damped Lyman- system (DLA, \nhi\ ) counterparts (33 detections, 12 upper limits) which host gamma-ray bursts (GRB…
An Ultraviolet Spectrum of the Tidal Disruption Flare ASASSN-14li
S. Bradley Cenko, Antonino Cucchiara, Nathaniel Roth +18
We present a Hubble Space Telescope STIS spectrum of ASASSN-14li, the first rest-frame UV spectrum of a tidal disruption flare (TDF). The underlying continuum is well fit by a blac…
First Search for an X-ray -- Optical Reverberation Signal in an Ultraluminous X-ray Source
Dheeraj R. Pasham, Tod E. Strohmayer, S. Bradley Cenko +3
Using simultaneous optical (VLT/FORS2) and X-ray (XMM-Newton) data of NGC 5408, we present the first ever attempt to search for a reverberation signal in an ultraluminous X-ray sou…
Evidence for High-Frequency QPOs with a 3:2 Frequency Ratio from a 5000 Solar Mass Black Hole
Dheeraj R. Pasham, S. Bradley Cenko, Abderahmen Zoghbi +3
Following the discovery of 3:2 resonance quasi-periodic oscillations (QPOs) in M82X-1 (Pasham et al. 2014), we have constructed power density spectra (PDS) of all 15 (sufficiently…
