Chasing Gravitational Waves with the Cherenkov Telescope Array
Jarred Gershon Green, Alessandro Carosi, Lara Nava +563
The detection of gravitational waves from a binary neutron star merger by Advanced LIGO and Advanced Virgo (GW170817), along with the discovery of the electromagnetic counterparts…
On the influence of high energy electron populations on metal abundance estimates in galaxy groups and clusters
Dmitry Prokhorov
Spectral line emissivities have usually been calculated for a Maxwellian electron distribution. But many theoretical works on galaxy groups and clusters and on the solar corona sug…
Missing baryons in shells around galaxy clusters
Dmitry Prokhorov
The cluster baryon fraction is estimated from the CMB-scattering leptonic component of the intracluster medium (ICM); however, the observed cluster baryon fraction is less than the…
Magnetic-field Order in the Southwestern Rim of RCW 86 Constrained Using X-Ray Polarimetry
Stefano Silvestri, Dmitry Prokhorov, Jacco Vink +97
RCW 86 is a supernova remnant whose origin has recently been linked to an off-center explosion within a cavity created by its progenitor star. In the southwestern region, the forwa…
X-ray polarization in SN 1006 southwest shows spatial variations and differences with the radio band
Ping Zhou, Patrick Slane, Dmitry Prokhorov +15
We report the detection of a spatial variation of X-ray polarization in the southwestern shell of SN 1006 (SN 1006 SW) using IXPE. The shell has an average X-ray polarization degre…
Potential of the Cherenkov Telescope Array for studying the young nearby supernova remnants
Dmitry Prokhorov, Shiu-Hang Lee, Shigehiro Nagataki +7
Modern imaging atmospheric Cherenkov telescopes have extensively observed young nearby supernova remnants (SNRs), with ages of about 1000 years or less, in the very-high-energy (VH…
Non-equilibrium ionization states in galaxy clusters
Dmitry Prokhorov
X-ray imaging observatories have revealed hydrodynamic structures with linear scales ~ 10 kpc in clusters of galaxies, such as shock waves in the 1E0657-56 and A520 galaxy clusters…
Discovery of a shock-compressed magnetic field in the north-western rim of the young supernova remnant RX J1713.7-3946 with X-ray polarimetry
Riccardo Ferrazzoli, Dmitry Prokhorov, Niccolò Bucciantini +99
Supernova remnants (SNRs) provide insights into cosmic-ray acceleration and magnetic field dynamics at shock fronts. Recent X-ray polarimetric measurements by the Imaging X-ray Pol…
X-ray polarimetry reveals the magnetic field topology on sub-parsec scales in Tycho's supernova remnant
Riccardo Ferrazzoli, Patrick Slane, Dmitry Prokhorov +97
Supernova remnants are commonly considered to produce most of the Galactic cosmic rays via diffusive shock acceleration. However, many questions about the physical conditions at sh…
LMC N132D: a mature supernova remnant with a youthful gamma-ray spectrum
Jacco Vink, Rachel Simoni, Nukri Komin +1
The supernova remnant LMC N132D is a remarkably luminous gamma-ray emitter at 50 kpc with an age of 2500 years. It belongs to the small group of oxygen-rich SNRs, which…
An update on Fermi-LAT transients in the Galactic plane, including strong activity of Cygnus X-3 in mid-2020
Dmitry Prokhorov, Anthony Moraghan
We present a search for Galactic transient gamma-ray sources using 13 years of the Fermi Large Area Telescope data. The search is based on a recently developed variable-size slidin…
X-ray polarization detection of Cassiopeia A with IXPE
Jacco Vink, Dmitry Prokhorov, Riccardo Ferrazzoli +92
We report on a detection of polarized 3-6 keV X-ray emission from the supernova remnant Cassiopeia A with the Imaging X-ray Polarimetry Explorer (IXPE). The overall pola…
The Post-impact Evolution of the X-ray Emitting Gas in SNR 1987A Viewed by XMM-Newton
Lei Sun, Jacco Vink, Yang Chen +4
Since 1996 the blast wave driven by SN 1987A has been interacting with the dense circumstellar material, which provides us with a unique opportunity to study the early evolution of…
Magnetic structures and turbulence in SN 1006 revealed with imaging X-ray polarimetry
Ping Zhou, Dmitry Prokhorov, Riccardo Ferrazzoli +99
Young supernova remnants (SNRs) strongly modify surrounding magnetic fields, which in turn play an essential role in accelerating cosmic rays (CRs). X-ray polarization measurements…
Deep observations of Kepler's SNR with H.E.S.S
Dmitry Prokhorov, Jacco Vink, Rachel Simoni +7
Kepler's supernova remnant (SNR) which is produced by the most recent naked-eye supernova in our Galaxy is one of the best studied SNRs, but its gamma-ray detection has eluded us s…
Search for gamma rays from SNe with a variable-size sliding-time-window analysis of the Fermi-LAT data
Dmitry Prokhorov, Anthony Moraghan, Jacco Vink
We present a systematic search for gamma-ray emission from supernovae (SNe) in the Fermi Large Area Telescope (LAT) Pass 8 data. The sample of targets consists of 55,880 candidates…
