Prompt Emission from Tidal Disruptions of White Dwarfs by Intermediate Mass Black Holes
Roman V. Shcherbakov, Asaf Pe'er, Christopher S. Reynolds +3
We present a qualitative picture of prompt emission from tidal disruptions of white dwarfs (WD) by intermediate mass black holes (IMBH). The smaller size of an IMBH compared to a s…

Bright radio emission from an ultraluminous stellar-mass microquasar in M31
Matthew J. Middleton, James C. A. Miller-Jones, Sera Markoff +34
A subset of ultraluminous X-ray sources (those with luminosities < 10^40 erg/s) are thought to be powered by the accretion of gas onto black holes with masses of ~5-20 M_solar, pro…

Constraining the Accretion Flow in Sgr A* by General Relativistic Dynamical and Polarized Radiative Modeling
Roman V. Shcherbakov, Robert F. Penna, Jonathan C. McKinney
We briefly summarize the method of simulating Sgr A* polarized sub-mm spectra from the accretion flow and fitting the observed spectrum. The dynamical flow model is based on three-…
Deviation of Stellar Orbits from Test Particle Trajectories Around Sgr A* Due to Tides and Winds
Dimitrios Psaltis, Gongjie Li, Abraham Loeb
Monitoring the orbits of stars around Sgr A* offers the possibility of detecting the precession of their orbital planes due to frame dragging, of measuring the spin and quadrupole…
The Chandra Local Volume Survey: The X-ray Point Source Population of NGC 404
B. Binder, B. F. Williams, M. Eracleous +4
We present a comprehensive X-ray point source catalog of NGC 404 obtained as part of the Chandra Local Volume Survey. A new, 97 ks Chandra ACIS-S observation of NGC 404 was combine…
High Frequency Gravitational Waves from Supermassive Black Holes: Prospects for LIGO-Virgo Detections
Bence Kocsis
It is commonly assumed that ground-based gravitational wave (GW) instruments will not be sensitive to supermassive black holes (SMBHs) because the characteristic GW frequencies are…
Radio Monitoring of the Tidal Disruption Event Swift J164449.3+573451. II. The Relativistic Jet Shuts Off and a Transition to Forward Shock X-ray/Radio Emission
B. A. Zauderer, E. Berger, R. Margutti +5
We present continued multi-frequency radio observations of the relativistic tidal disruption event Sw1644+57 extending to dt~600 d. The data were obtained with the JVLA and AMI Lar…
Chandra Observations of the Collisional Ring Galaxy NGC 922
A. H. Prestwich, J. L. Galache. T. Linden, V. Kalogara +5
In this paper we report on Chandra observations of the starburst galaxy NGC 922. NGC 922 is a drop-through ring galaxy with an expanding ring of star formation, similar in many res…
Multiwavelength observations of GRB 110731A: GeV emission from onset to afterglow
LAT Collaboration, GBM Collaboration, Swift Collaboration +2
We report on the multiwavelength observations of the bright, long gamma-ray burst \GRB, by the \Fermi and \Swift observatories, and by the MOA and GROND optical telescopes. The ana…
Jet Power and Black Hole Spin: Testing an Empirical Relationship and Using it to Predict the Spins of Six Black Holes
James F. Steiner, Jeffrey E. McClintock, Ramesh Narayan
Using 5 GHz radio luminosity at light-curve maximum as a proxy for jet power and black-hole spin measurements obtained via the continuum-fitting method, Narayan & McClintock (2012)…
