Long duration Gamma-Ray Bursts (LGRBs) may serve as standard candles to constrain cosmological parameters by probing the Hubble diagram well beyond the range of redshift currently…
The NANOGrav 11-Year Data Set: Evolution of Gravitational Wave Background Statistics
J. S. Hazboun, J. Simon, S. R. Taylor +60
An ensemble of inspiraling supermassive black hole binaries should produce a stochastic background of very low frequency gravitational waves. This stochastic background is predicte…
The International Pulsar Timing Array: Second data release

In this paper, we describe the International Pulsar Timing Array second data release, which includes recent pulsar timing data obtained by three regional consortia: the European Pu…
The Fermi GBM GRBs' multivariate statistics
Istvan I. Racz, Lajos G. Balázs, Zsolt Bagoly +2
Studying the GRBs' gamma-ray spectra may reveal some physical information of Gamma-ray Bursts. The Fermi satellite observed more than two thousand GRBs. The FERMIGBRST catalog cont…
Studying the variability of the X-ray spectral parameters of high-redshift GRBs' afterglows
Istvan I. Racz, Agnes J. Hortobagyi
The Swift satellite has observed more than a thousand GRBs with X-ray data. Almost a third of them have redshift measurement, too. Here we start to investigate the X-ray spectral f…
Estimation of the detected background by the future gamma-ray transient mission CAMELOT
J. Ripa, G. Galgóczi, N. Werner +18
This study presents a background estimation for the Cubesats Applied for MEasuring and LOcalising Transients (CAMELOT), which is a proposed fleet of nanosatellites for the all-sky…
An Optically Targeted Search for Gravitational Waves emitted by Core-Collapse Supernovae during the First and Second Observing Runs of Advanced LIGO and Advanced Virgo
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1195
We present the results from a search for gravitational-wave transients associated with core-collapse supernovae observed within a source distance of approximately 20 Mpc during the…
Electromagnetic transients and gravitational waves from white dwarf disruptions by stellar black holes in triple systems
Giacomo Fragione, Brian D. Metzger, Rosalba Perna +2
Mergers of binaries comprised of compact objects can give rise to explosive transient events, heralding the birth of exotic objects which cannot be formed through single star evolu…

The high-resolution X-ray spectrum of the Perseus galaxy cluster observed with the Hitomi satellite challenges astrophysical collisional ionized plasma models that are widely used…
Observations of a Pre-Merger Shock in Colliding Clusters of Galaxies
Liyi Gu, Hiroki Akamatsu, Timothy W. Shimwell +10
Clusters of galaxies are the largest known gravitationally-bound structures in the Universe. When clusters collide, they create merger shocks on cosmological scales, which transfor…
