Constraining bright optical counterparts of Fast Radio Bursts
C. Nuñez, N. Tejos, G. Pignata +14
Fast Radio Bursts (FRBs) are extremely energetic pulses of millisecond duration and unknown origin. In order to understand the phenomenon that emits these pulses, targeted and unta…

Multiwavelength Follow-up of the Hyperluminous Intermediate-mass Black Hole Candidate 3XMM J215022.4-055108
Dacheng Lin, Jay Strader, Aaron J. Romanowsky +6
We recently discovered the X-ray/optical outbursting source 3XMM J215022.4-055108. It was best explained as the tidal disruption of a star by an intermediate-mass black hole of mas…
A luminous X-ray outburst from an intermediate-mass black hole in an off-centre star cluster
Dacheng Lin, Jay Strader, Eleazar R. Carrasco +13
A unique signature for the presence of massive black holes in very dense stellar regions is occasional giant-amplitude outbursts of multiwavelength radiation from tidal disruption…
The Cocoon Shocks of Cygnus A: Pressures and Their Implications for the Jets and Lobes
Bradford Snios, Paul E. J. Nulsen, Michael W. Wise +18
We use 2.0 Msec of Chandra observations to investigate the cocoon shocks of Cygnus A and some implications for its lobes and jet. Measured shock Mach numbers vary in the range 1.18…
The X-ray Ribs Within the Cocoon Shock of Cygnus A

We use new and archival Chandra observations of Cygnus A, totalling 1.9 Ms, to investigate the distribution and temperature structure of gas lying within the projected extent…
Constraints on Cosmic-ray Acceleration Efficiency in Balmer Shocks of Two Young Type Ia Supernova Remnants in the Large Magellanic Cloud
Luke Hovey, John P. Hughes, Curtis McCully +2
We present results from an optical study of two young Balmer-dominated remnants of SNIa in the Large Magellanic Cloud, 050967.5 and 051969.0, in an attempt to search for sign…
Gaia17biu/SN 2017egm in NGC 3191: The closest hydrogen-poor superluminous supernova to date is in a "normal", massive, metal-rich spiral galaxy
Subhash Bose, Subo Dong, A. Pastorello +55
Hydrogen-poor superluminous supernovae (SLSNe-I) have been predominantly found in low-metallicity, star-forming dwarf galaxies. Here we identify Gaia17biu/SN 2017egm as an SLSN-I o…

William G. Mathews
Cosmic rays, thermal gas and magnetic fields in FRII radio cavities are assumed to come entirely from winds flowing from just behind the jet shocks. Combining analytic and computat…
