Variability studies of active galactic nuclei from the long-term monitoring program with the Cherenkov Telescope Array

Guillaume Grolleron, Josefa Becerra González, Jonathan Biteau +13

Blazars are active galactic nuclei (AGN) with a relativistic jet oriented toward the observer. This jet is composed of accelerated particles which can display emission over the ent…

Probing the nature of the X-ray source IGR J16327-4940 with Chandra

L. Sidoli, V. Sguera, K. Postnov +3

We report on the results of a Chandra observation of the source IGRJ16327-4940, suggested to be a high mass X-ray binary hosting a luminous blue variable star (LBV). The source fie…

Dark matter searches in dwarf spheroidal galaxies with the Cherenkov Telescope Array

Francesco Gabriele Saturni, Michele Doro, Aldo Morselli +1

Dark matter (DM) is one of the major components in the Universe. However, at present its existence is still only inferred through indirect astronomical observations. DM particles c…

Prospects for -ray observations of the Perseus galaxy cluster with the Cherenkov Telescope Array

The Cherenkov Telescope Array Consortium, :, K. Abe +564

Galaxy clusters are expected to be dark matter (DM) reservoirs and storage rooms for the cosmic-ray protons (CRp) that accumulate along the cluster's formation history. Accordingly…

The power of the rings: the GRB 221009A soft X-ray emission from its dust-scattering halo

Andrea Tiengo, Fabio Pintore, Beatrice Vaia +11

GRB 221009A is the brightest gamma-ray burst (GRB) ever detected and occurred at low Galactic latitude. Owing to this exceptional combination, its prompt X-ray emission could be de…

X-ray nondetection of PSR J0250+5854

C. M. Tan, M. Rigoselli, P. Esposito +1

We conducted a deep XMM$\unicode{x2013}$Newton observing campaign on the 23.5-s radio pulsar PSR J0250+5854 in order to better understand the connection between long-period, radio-…
