Multi-wavelength campaign on NGC7469 I. The rich 640 ks RGS spectrum
Ehud Behar, Uria Peretz, Gerard A. Kriss +15
Outflows in active galaxies (AGNs) are common, although their launching mechanism, location, and physical impact on the host galaxy remain controversial. We conducted a multiwavele…
Suzaku observations of the merging galaxy cluster Abell2255: The northeast radio relic
H. Akamatsu, M. Mizuno, N. Ota +12
We present the results of deep 140 ks Suzaku X-ray observations of the north-east (NE) radio relic of the merging galaxy cluster Abell2255. The temperature structure of Abell2255 i…
The electron energy-loss rate due to radiative recombination
Junjie Mao, Jelle Kaastra, N. R. Badnell
For photoionized plasmas, electron energy-loss rates due to radiative recombination (RR) are required for thermal equilib- rium calculations, which assume a local balance between t…
Search for high-energy neutrinos from bright GRBs with ANTARES
A. Albert, M. André, M. Anghinolfi +125
Gamma-ray bursts are thought to be sites of hadronic acceleration, thus neutrinos are expected from the decay of charged particles, produced in pγ interactions. The methods and res…
Results from the search for dark matter in the Milky Way with 9 years of data of the ANTARES neutrino telescope
A. Albert, M. André, M. Anghinolfi +125
Using data recorded with the ANTARES telescope from 2007 to 2015, a new search for dark matter annihilation in the Milky Way has been performed. Three halo models and five annihila…
The Slow Orbital Evolution of the Accreting Millisecond Pulsar IGR J0029+5934
A. Patruno
The accreting millisecond pulsars IGR J00291+5934 and SAX J1808.4-3658 are two compact binaries with very similar orbital parameters. The latter has been observed to evolve on a ve…
Radio pulse search and X-Ray monitoring of SAX J1808.4-3658: What Causes its Orbital Evolution?
Alessandro Patruno, Amruta Jaodand, Lucien Kuiper +6
The accreting millisecond X-ray pulsar (AMXP) SAX J1808.4-3658, shows a peculiar orbital evolution that proceeds at a much faster pace than predicted by conservative binary evoluti…
High-resolution X-ray spectroscopy: the coming-of-age
J. S. Kaastra
Since the launch of Chandra and XMM-Newton, high-resolution X-ray spectra of cosmic sources of all kinds have become available. These spectra have resulted in major scientific brea…
CHEERS: Future perspectives for abundance measurements in clusters with XMM-Newton
J. de Plaa, F. Mernier
The CHEERS (CHEmical Enrichment RGS Sample) observations of clusters of galaxies with XMM-Newton have shown to be valuable to constrain the chemical evolution of the universe. The…
Magnetic field evolution in tidal disruption events
Clément Bonnerot, Daniel J. Price, Giuseppe Lodato +1
When a star gets tidally disrupted by a supermassive black hole, its magnetic field is expected to pervade its debris. In this paper, we study this process via smoothed particle ma…
Systematic comparison of photoionised plasma codes with application to spectroscopic studies of AGN in X-rays
M. Mehdipour, J. S. Kaastra, T. Kallman
Atomic data and plasma models play a crucial role in the diagnosis and interpretation of astrophysical spectra, thus influencing our understanding of the universe. In this investig…
Timing Observations of PSR J1023+0038 During a Low-Mass X-ray Binary State
Amruta Jaodand, Anne M. Archibald, Jason W. T. Hessels +5
Transitional millisecond pulsars (tMSPs) switch, on roughly multi-year timescales, between rotation-powered radio millisecond pulsar (RMSP) and accretion-powered low-mass X-ray bin…
The second closest gamma-ray burst: sub-luminous GRB 111005A with no supernova in a super-solar metallicity environment
Michał J. Michałowski, Dong Xu, Jamie Stevens +17
We report the detection of the radio afterglow of a long gamma-ray burst (GRB) 111005A at 5-345 GHz, including the very long baseline interferometry observations with the positiona…
The MHz-peaked radio spectrum of the unusual gamma-ray source PMN J1603-4904
C. Müller, P. R. Burd, R. Schulz +6
Context. The majority of bright extragalactic gamma-ray sources are blazars. Only a few radio galaxies have been detected by Fermi/LAT. Recently, the GHz-peaked spectrum source PKS…
Time-dependent search for neutrino emission from x-ray binaries with the ANTARES telescope
A. Albert, M. André, G. Anton +115
ANTARES is currently the largest neutrino telescope operating in the Northern Hemisphere, aiming at the detection of high-energy neutrinos from astrophysical sources. Neutrino tele…
Laboratory measurements compellingly support charge-exchange mechanism for the 'dark matter' 3.5 keV X-ray line
Chintan Shah, Stepan Dobrodey, Sven Bernitt +4
The reported observations of an unidentified X-ray line feature at 3.5 keV have driven a lively discussion about its possible dark matter origin. Motivated by this, we have m…
and observations of a newly-discovered early-stage cluster merger 1E2216.0-0401 and 1E2215.7-0404
H. Akamatsu, L. Gu, T. W. Shimwell +6
We present the results of and X-ray observations of the cluster pair 1E2216.0-0401 and 1E2215.7-0404. We discover an X-ray bridge between the clusters. $Suzak…
Long-term stream evolution in tidal disruption events
Clément Bonnerot, Elena M. Rossi, Giuseppe Lodato
A large number of tidal disruption event (TDE) candidates have been observed recently, often differing in their observational features. Two classes appear to stand out: X-ray and o…
Suzaku and XMM-Newton Observations of the North Polar Spur: Charge Exchange or ISM Absorption?
Liyi Gu, Junjie Mao, Elisa Costantini +1
By revisiting the Suzaku and XMM-Newton data of the North Polar Spur, we discovered that the spectra are inconsistent with the traditional model consisting of pure thermal emission…

This study aims to probe the thermodynamic properties of the hot intragroup medium (IGM) plasma in the core regions of the NGC 4636 galaxy group by detailed measurements of several…
Black holes in stellar-mass binary systems: expiating original spin?
Andrew King, Chris Nixon
We investigate systematically whether accreting black hole systems are likely to reach global alignment of the black hole spin and its accretion disc with the binary plane. In low-…
Geometrical beaming of stellar mass ULXs
Matthew Middleton, Andrew King
The presence or lack of eclipses in the X-ray lightcurves of ultraluminous X-ray sources (ULXs) can be directly linked to the accreting system geometry. In the case where the compa…
