Detectable environmental effects in GW190521-like black-hole binaries with LISA

Alexandre Toubiana, Laura Sberna, Andrea Caputo +9

GW190521 is the compact binary with the largest masses observed to date, with at least one in the pair-instability gap. This event has also been claimed to be associated with an op…

Monitoring the Morphology of M87* in 2009-2017 with the Event Horizon Telescope

Maciek Wielgus, Kazunori Akiyama, Lindy Blackburn +26

The Event Horizon Telescope (EHT) has recently delivered the first resolved images of M87*, the supermassive black hole in the center of the M87 galaxy. These images were produced…

Candidate Periodically Variable Quasars from the Dark Energy Survey and the Sloan Digital Sky Survey

Yu-Ching Chen, Xin Liu, Wei-Ting Liao +62

Periodically variable quasars have been suggested as close binary supermassive black holes. We present a systematic search for periodic light curves in 625 spectroscopically confir…

A DESGW Search for the Electromagnetic Counterpart to the LIGO/Virgo Gravitational Wave Binary Neutron Star Merger Candidate S190510g

DES Collaboration, A. Garcia, R. Morgan +87

We present the results from a search for the electromagnetic counterpart of the LIGO/Virgo event S190510g using the Dark Energy Camera (DECam). S190510g is a binary neutron star (B…

Observation of inverse Compton emission from a long -ray burst

V. A. Acciari, S. Ansoldi, L. A. Antonelli +301

Long-duration gamma-ray bursts (GRBs) originate from ultra-relativistic jets launched from the collapsing cores of dying massive stars. They are characterised by an initial phase o…

Teraelectronvolt emission from the -ray burst GRB 190114C

MAGIC Collaboration, V. A. Acciari, S. Ansoldi +177

Gamma-ray bursts (GRBs) of the long-duration class are the most luminous sources of electromagnetic radiation known in the Universe. They are generated by outflows of plasma ejecte…
