Accretion geometry of the neutron star low mass X-ray binary Cyg X-2 from X-ray polarization measurements
R. Farinelli, S. Fabiani, J. Poutanen +92
We report spectro-polarimetric results of an observational campaign of the bright neutron star low-mass X-ray binary Cyg X-2 simultaneously observed by IXPE, NICER and INTEGRAL. Co…
Polarization properties of the weakly magnetized neutron star X-ray binary GS 1826-238 in the high soft state
Fiamma Capitanio, Sergio Fabiani, Andrea Gnarini +94
The launch of the Imaging X-ray Polarimetry Explorer (IXPE) on 2021 December 9 has opened a new window in X-ray astronomy. We report here the results of the first IXPE observation…
The interconnection between galaxy mergers, AGN activity and rapid quenching of star formation in simulated post-merger galaxies
Salvatore Quai, Shoshannah Byrne-Mamahit, Sara L. Ellison +2
We investigate the role of galaxy mergers on supermassive black hole (SMBH) accretion and star formation quenching in three state-of-the-art cosmological simulations with contrasti…
Multiple shock fronts in RBS 797: the Chandra window on shock heating in galaxy clusters
F. Ubertosi, M. Gitti, F. Brighenti +11
Using 427 ks of Chandra observations, we present a study of shock heating and ICM cooling in the galaxy cluster RBS 797. We discover three nested pairs of weak shocks at roug…
Using Machine Learning to Determine Morphologies of AGN Host Galaxies in the Hyper Suprime-Cam Wide Survey
Chuan Tian, C. Megan Urry, Aritra Ghosh +9
We present a machine-learning framework to accurately characterize morphologies of Active Galactic Nucleus (AGN) host galaxies within . We first use PSFGAN to decouple host ga…
DDO68 C: the actual appearance of a ghost satellite dwarf through adaptive optics at the Large Binocular Telescope
Francesca Annibali, Enrico Pinna, Leslie K. Hunt +12
Through adaptive optics (AO) imaging with the SOUL+LUCI instrument at the Large Binocular Telescope we were able to resolve, for the first time, individual stars in the gas-rich ga…
