Deep XMM-Newton observation reveals hot gaseous outflow in NGC 5746
Roman Laktionov, Manami Sasaki, Jörn Wilms
We present a deep XMM-Newton observation of the massive, edge-on galaxy NGC 5746. The total exposure time of 250 ks provides unprecedented sensitivity to study the diffuse hot gas…
The most distant -ray flare to date: a multiwavelength campaign on the blazar GB6 B1428+4217
Andrea Gokus, Manel Errando, Ivan Agudo +12
In November 2023, the Fermi Large Area Telescope detected a -ray flare from the high-redshift blazar GB6 B1428+4217 (). We initiated a multi-wavelength follow-up campai…
A gamma-ray flare from TXS 1508+572: characterizing the jet of a blazar in the early Universe
Andrea Gokus, Markus Böttcher, Manel Errando +13
Blazars can be detected from very large distances due to their high luminosity. However, the detection of -ray emission of blazars beyond has only been confirmed for a sma…
TELAMON: Effelsberg Monitoring of AGN Jets with Very-High-Energy Astroparticle Emissions -- Polarization properties
J. Heßdörfer, M. Kadler, P. Benke +33
We present recent results of the TELAMON program, which is using the Effelsberg 100-m telescope to monitor the radio spectra of active galactic nuclei (AGN) under scrutiny in astro…
Drop in the hard pulsed fraction and a candidate cyclotron line in IGR J16320-4751 seen by NuSTAR
Arash Bodaghee, Alan J. -L. Chiu, John A. Tomsick +10
We report on a timing and spectral analysis of a 50-ks NuSTAR observation of IGR J16320-4751 (= AX J1631.9-4752); a high-mass X-ray binary hosting a slowly-rotating neutron star. I…
Vacuum polarization alters the spectra of accreting X-ray pulsars
E. Sokolova-Lapa, J. Stierhof, T. Dauser +1
It is a common belief that for magnetic fields typical for accreting neutron stars in High-Mass X-ray Binaries vacuum polarization only affects the propagation of polarized emissio…
