Electromagnetic vs. Lense-Thirring alignment of black hole accretion discs
Peter Polko, Jonathan C. McKinney
Accretion discs and black holes (BHs) have angular momenta that are generally misaligned with respect to each other, which can lead to warps in the discs and bends in any jets prod…
Testing the Propagating Fluctuations Model with a Long, Global Accretion Disk Simulation
J. Drew Hogg, Christopher Reynolds
The broad-band variability of many accreting systems displays characteristic structure; log-normal flux distributions, RMS-flux relations, and long inter-band lags. These character…
Resolved Magnetic-Field Structure and Variability Near the Event Horizon of Sagittarius A*
Michael D. Johnson, Vincent L. Fish, Sheperd S. Doeleman +45
Near a black hole, differential rotation of a magnetized accretion disk is thought to produce an instability that amplifies weak magnetic fields, driving accretion and outflow. The…
Deja Vu All Over Again: The Reappearance of Supernova Refsdal
P. L. Kelly, S. A. Rodney, T. Treu +21
In Hubble Space Telescope (HST) imaging taken on 10 November 2014, four images of supernova (SN) "Refsdal" (redshift z=1.49) appeared in an Einstein-cross--like configuration (imag…
Radio observations of a sample of broad-lined type Ic supernovae discovered by PTF/iPTF: A search for relativistic explosions
A. Corsi, A. Gal-Yam, S. R. Kulkarni +15
Long duration gamma-ray bursts are a rare subclass of stripped-envelope core-collapse supernovae that launch collimated relativistic outflows (jets). All gamma-ray-burst-associated…
Type II supernova energetics and comparison of light curves to shock-cooling models
Adam Rubin, Avishay Gal-Yam, Annalisa De Cia +37
During the first few days after explosion, Type II supernovae (SNe) are dominated by relatively simple physics. Theoretical predictions regarding early-time SN light curves in the…
Inefficient Driving of Bulk Turbulence by Active Galactic Nuclei in a Hydrodynamic Model of the Intracluster Medium
Christopher S. Reynolds, Steven A. Balbus, Alexander A. Schekochihin
Central jetted active galactic nuclei (AGN) appear to heat the core regions of the intracluster medium (ICM) in cooling-core galaxy clusters and groups, thereby preventing a coolin…
On the relation of optical obscuration and X-ray absorption in Seyfert galaxies
L. Burtscher, R. I. Davies, J. Gracia-Carpio +15
The optical classification of a Seyfert galaxy and whether it is considered X-ray absorbed are often used interchangeably. But there are many borderline cases and also numerous exa…
Rapidly Rising Transients in the Supernova - Superluminous Supernova Gap
Iair Arcavi, William M. Wolf, D. Andrew Howell +26
We present observations of four rapidly rising (t_{rise}~10d) transients with peak luminosities between those of supernovae (SNe) and superluminous SNe (M_{peak}~-20) - one discove…
Unwrapping the X-ray Spectra of Active Galactic Nuclei
Christopher S. Reynolds
Active galactic nuclei (AGN) are complex phenomena. At the heart of an AGN is a relativistic accretion disk around a spinning supermassive black hole (SMBH) with an X-ray emitting…
Flows of X-ray gas reveal the disruption of a star by a massive black hole
Jon M. Miller, Jelle S. Kaastra, M. Coleman Miller +18
Tidal forces close to massive black holes can violently disrupt stars that make a close approach. These extreme events are discovered via bright X-ray and optical/UV flares in gala…
Tidal Disruption Events by a Massive Black Hole Binary
Angelo Ricarte, Priyamvada Natarajan, Lixin Dai +1
Massive black hole binaries (MBHBs) are a natural byproduct of galaxy mergers. Previous studies have shown that flares from stellar tidal disruption events (TDEs) are modified by t…
Happy Birthday Swift: Ultra-long GRB141121A and its broad-band Afterglow
A. Cucchiara, P. Veres, A. Corsi +27
We present our extensive observational campaign on the Swift-discovered GRB141121A, al- most ten years after its launch. Our observations covers radio through X-rays, and extends f…
Jet Signatures in the Spectra of Accreting Black Holes
Michael O' Riordan, Asaf Pe'er, Jonathan C. McKinney
Jets are observed as radio emission in active galactic nuclei and during the low/hard state in X-ray binaries (XRBs), but their contribution at higher frequencies has been uncertai…
X-ray Burst Oscillations: From Flame Spreading to the Cooling Wake
Simin Mahmoodifar, Tod Strohmayer
Type I X-ray bursts are thermonuclear flashes observed from the surfaces of accreting neutron stars (NSs) in Low Mass X-ray Binaries. Oscillations have been observed during the ris…
Late time multi wavelength observations of Swift J1644+5734: A luminous optical/IR bump and quiescent X-ray emission
A. J. Levan, N. R. Tanvir, G. C. Brown +10
We present late-time multi-wavelength observations of Swift J1644+57, suggested to be a relativistic tidal disruption flare (TDF). Our observations extend to >4 years from discover…
What Powers the 3000-Day Light Curve of SN 2006gy?
Ori D. Fox, Nathan Smith, S. Mark Ammons +11
SN 2006gy was the most luminous SN ever observed at the time of its discovery and the first of the newly defined class of superluminous supernovae (SLSNe). The extraordinary energe…
A test of the nature of the Fe K Line in the neutron star low-mass X-ray binary Serpens X-1
Chia-Ying Chiang, Edward M. Cackett, Jon M. Miller +12
Broad Fe K emission lines have been widely observed in the X-ray spectra of black hole systems, and in neutron star systems as well. The intrinsically narrow Fe K fluorescent line…
