Constraining AGN accretion physics with black hole mass-luminosity scaling relations
F. Fiore, M. Gaspari, S. Puccetti +3
We test how supermassive black holes are fed by combining new black hole mass-luminosity relations with physically motivated feeding models. We build a uniform sample of 1729 unobs…
Ultra-thick warm absorbers: Enlarging the parameter space of AGN ionised outflows
R. Middei, E. Piconcelli, E. Nardini +9
The analysis of X-ray absorption features in active galactic nuclei (AGN) provides a wealth of information about the physical properties of the matter surrounding supermassive blac…
CubeSats Reach the Millisecond X-Ray Domain: Crab Pulsar Timing with SpIRIT/HERMES
Wladimiro Leone, R. Mearns, T. Di Salvo +70
The High Energy Rapid Modular Ensemble of Satellites (HERMES) instrument is a compact X/-ray spectrometer operating on board the 6U (11 kg) SpIRIT CubeSat. The payload is parti…
IXPE Observations of the Blazar Mrk 501 in 2022: A Multiwavelength View
L. Lisalda, E. Gau, H. Krawczynski +157
The blazar Markarian 501 (Mrk 501) was observed on three occasions over a 4-month period between 2022 March and 2022 July with the Imaging X-ray Polarimetry Explorer (IXPE). In thi…
