Pulsating ULXs: large pulsed fraction excludes strong beaming
Alexander A. Mushtukov, Simon Portegies Zwart, Sergey S. Tsygankov +2
The recent discovery of pulsating ultra-luminous X-ray sources (ULXs) shows that the apparent luminosity of accreting neutron stars (NSs) can exceed the Eddington luminosity by a f…
Diffuse Radio Emission from Galaxy Clusters in the LOFAR Two-metre Sky Survey Deep Fields
E. Osinga, R. J. van Weeren, J. Boxelaar +15

The presence of non-thermal electrons and large scale magnetic fields in the intra-cluster medium (ICM) is known through the detection of mega-parsec (Mpc) scale diffuse radio sync…
ANTARES upper limits on the multi-TeV neutrino emission from the GRBs detected by IACTs
ANTARES Collaboration, A. Albert, M. André +135
The first gamma-ray burst detections by Imaging Atmospheric Cherenkov Telescopes have been recently announced: GRB 190114C, detected by MAGIC, GRB 180720B and GRB 190829A, observed…
Substructures in the core of Abell 2319
Y. Ichinohe, A. Simionescu, N. Werner +2
We analysed the deep archival Chandra observations of the high-temperature galaxy cluster Abell 2319 to investigate the prominent cold front in its core. The main sharp arc of the…
A Family Tree of Optical Transients from Narrow-Line Seyfert 1 Galaxies
Sara Frederick, Suvi Gezari, Matthew J. Graham +17
The Zwicky Transient Facility (ZTF) has discovered five new events belonging to an emerging class of AGN undergoing smooth flares with large amplitudes and rapid rise times. This s…
Monte Carlo simulations for the ANTARES underwater neutrino telescope
The ANTARES Collaboration, A. Albert, M. André +133
Monte Carlo simulations are a unique tool to check the response of a detector and to monitor its performance. For a deep-sea neutrino telescope, the variability of the environmenta…
Search for Gravitational Waves Associated with Gamma-Ray Bursts Detected by Fermi and Swift During the LIGO-Virgo Run O3a
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1250
We search for gravitational-wave transients associated with gamma-ray bursts detected by the Fermi and Swift satellites during the first part of the third observing run of Advanced…

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…
ClG 0217+70: A massive merging galaxy cluster with a large radio halo and relics
X. Zhang, A. Simionescu, J. S. Kaastra +7
We present an analysis of archival Chandra data of the merging galaxy cluster ClG 0217+70. The Fe XXV He X-ray emission line is clearly visible in the 25 ks observation, allowin…
Dynamically important magnetic fields near the event horizon of Sgr A*
GRAVITY Collaboration, A. Jiménez-Rosales, J. Dexter +53
We study the time-variable linear polarisation of Sgr A* during a bright NIR flare observed with the GRAVITY instrument on July 28, 2018. Motivated by the time evolution of both th…
