X-ray Brightening and UV Fading of Tidal Disruption Event ASASSN-15oi
S. Gezari, S. B. Cenko, I. Arcavi
We present late-time observations by Swift and XMM-Newton of the tidal disruption event (TDE) ASASSN-15oi that reveal that the source brightened in the X-rays by a factor of $\sim1…
Observational Signatures of Mass-Loading in Jets Launched by Rotating Black Holes
Michael O' Riordan, Asaf Pe'er, Jonathan C. McKinney
It is widely believed that relativistic jets in X-ray binaries and active-galactic nuclei are powered by the rotational energy of black holes. This idea is supported by general-rel…
Exploring The Effects Of Disk Thickness On The Black Hole Reflection Spectrum
Corbin Taylor, Christopher S. Reynolds
The relativistically-broadened reflection spectrum, observed in both AGN and X-ray binaries, has proven to be a powerful probe of the properties of black holes and the environments…
Sifting for Sapphires: Systematic Selection of Tidal Disruption Events in iPTF
T. Hung, S. Gezari, S. B. Cenko +15
We present results from a systematic selection of tidal disruption events (TDEs) in a wide-area (4800~deg), band, Intermediate Palomar Transient Factory (iPTF) experiment…
A Strong Test of the Dark Matter Origin of the 1.4 TeV DAMPE Signal Using IceCube Neutrinos
Yue Zhao, Ke Fang, Meng Su +1
A tentative excess in the electron spectrum at 1.4 TeV was recently reported by the DArk Matter Particle Explorer (DAMPE). A non-astrophysical scenario in which dark matter particl…
Ultrafast Outflow in Tidal Disruption Event ASASSN-14li
E. Kara, L. Dai, C. S. Reynolds +1
At only 90 Mpc, ASASSN-14li is one of the nearest tidal disruption event (TDE) ever discovered, and because of this, it has been observed by several observatories at many wavelengt…
Energetic eruptions leading to a peculiar hydrogen-rich explosion of a massive star
Iair Arcavi, D. Andrew Howell, Daniel Kasen +50
Every supernova hitherto observed has been considered to be the terminal explosion of a star. Moreover, all supernovae with absorption lines in their spectra show those lines decre…
The jet/wind outflow in Centaurus A: a local laboratory for AGN feedback
B. McKinley, S. J. Tingay, E. Carretti +20
We present new radio and optical images of the nearest radio galaxy Centaurus A and its host galaxy NGC 5128. We focus our investigation on the northern transition region, where en…
Ultra-High Energy Cosmic Rays and Neutrinos from Tidal Disruptions by Massive Black Holes
Claire Guépin, Kumiko Kotera, Enrico Barausse +2
Tidal disruptions are extremely powerful phenomena that have been designated as candidate sources of ultra-high-energy cosmic rays. The disruption of a star by a black hole can nat…
iPTF Survey for Cool Transients
S. M. Adams, N. Blagorodnova, M. M. Kasliwal +25
We performed a wide-area (2000 deg) g and I band experiment as part of a two month extension to the Intermediate Palomar Transient Factory. We discovered 36 extragalactic tra…
The Parsec-Scale Relationship Between I_CO and A_V in Local Molecular Clouds
Cheoljong Lee, Adam K. Leroy, Alberto D. Bolatto +4
We measure the parsec-scale relationship between integrated CO intensity (I_CO) and visual extinction (A_V) in 24 local molecular clouds using maps of CO emission and dust optical…
NuSTAR view of the black hole wind in the galaxy merger IRAS F111193257
F. Tombesi, S. Veilleux, M. Melendez +5
Galactic winds driven by active galactic nuclei (AGN) have been invoked to play a fundamental role in the co-evolution between supermassive black holes and their host galaxies. Fin…
A Deep Chandra X-ray Study of Neutron Star Coalescence GW170817
Daryl Haggard, Melania Nynka, John J. Ruan +4
We report Chandra observations of GW170817, the first neutron star-neutron star merger discovered by the joint LIGO-Virgo Collaboration, and the first direct detection of gravitati…
Optical Follow-up of Gravitational-wave Events with Las Cumbres Observatory
Iair Arcavi, Curtis McCully, Griffin Hosseinzadeh +11
We present an implementation of the Gehrels et al. (2016) galaxy-targeted strategy for gravitational-wave (GW) follow-up using the Las Cumbres Observatory global network of telesco…
The environment of the binary neutron star merger GW170817
A. J. Levan, J. D. Lyman, N. R. Tanvir +37
We present Hubble Space Telescope and Chandra imaging, combined with Very Large Telescope MUSE integral field spectroscopy of the counterpart and host galaxy of the first binary ne…
Swift and NuSTAR observations of GW170817: detection of a blue kilonova
P. A. Evans, S. B. Cenko, J. A. Kennea +56
With the first direct detection of merging black holes in 2015, the era of gravitational wave (GW) astrophysics began. A complete picture of compact object mergers, however, requir…
Illuminating Gravitational Waves: A Concordant Picture of Photons from a Neutron Star Merger
M. M. Kasliwal, E. Nakar, L. P. Singer +78
Merging neutron stars offer an exquisite laboratory for simultaneously studying strong-field gravity and matter in extreme environments. We establish the physical association of an…
The X-ray counterpart to the gravitational wave event GW 170817
E. Troja, L. Piro, H. van Eerten +31
A long-standing paradigm in astrophysics is that collisions- or mergers- of two neutron stars (NSs) form highly relativistic and collimated outflows (jets) powering gamma-ray burst…
