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…
Performance update of an event-type based analysis for the Cherenkov Telescope Array
Juan Bernete, Orel Gueta, Tarek Hassan +3
The Cherenkov Telescope Array (CTA) will be the next-generation observatory in the field of very-high-energy (20 GeV to 300 TeV) gamma-ray astroparticle physics. The traditional ap…
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…
Detecting and characterizing pulsar haloes with the Cherenkov Telescope Array
Christopher Eckner, Veronika Vodeb, Pierrick Martin +2
The recently identified source class of pulsar haloes may be numerous and bright enough in the TeV range to constitute a large fraction of the sources that will be observed with th…
Population synthesis of pulsar wind nebulae and pulsar halos in the Milky Way -- Predicted contributions to the very-high-energy sky
Pierrick Martin, Luigi Tibaldo, Alexandre Marcowith +1
The discovery of extended gamma-ray emission toward a number of middle-aged pulsars suggests the possibility of long-lived particle confinement beyond the classical pulsar wind neb…
Are pulsar halos rare ?
Pierrick Martin, Alexandre Marcowith, Luigi Tibaldo
Extended gamma-ray emission, interpreted as halos formed by the inverse-Compton scattering of ambient photons by electron-positron pairs, is observed toward a number of middle-aged…
The carbon footprint of IRAP
Pierrick Martin, Sylvie Brau-Nogué, Mickael Coriat +4
We present an assessment of the greenhouse gases emissions of the Institute for Research in Astrophysics and Planetology (IRAP), located in Toulouse (France). It was performed foll…
Estimate of the carbon footprint of astronomical research infrastructures
Jürgen Knödlseder, Sylvie Brau-Nogué, Mickael Coriat +4
The carbon footprint of astronomical research is an increasingly topical issue with first estimates of research institute and national community footprints having recently been pub…
Steady-state nucleosynthesis throughout the Galaxy
Roland Diehl, Martin G. H. Krause, Karsten Kretschmer +6
Measurement and astrophysical interpretation of characteristic gamma-ray lines from nucleosynthesis was one of the prominent science goals of the INTEGRAL mission and in particular…
Analysis of the H.E.S.S. public data release with ctools
Jürgen Knödlseder, Luigi Tibaldo, Domenico Tiziani +13
The ctools open-source software package was developed for the scientific analysis of astronomical data from Imaging Air Cherenkov Telescopes (IACTs), such as H.E.S.S., VERITAS, MAG…
Positron Annihilation in the Galaxy
Carolyn A. Kierans, John F. Beacom, Steve Boggs +27
The 511 keV line from positron annihilation in the Galaxy was the first -ray line detected to originate from outside our solar system. Going into the fifth decade since the disc…
Millisecond pulsar origin of the Galactic center excess and extended gamma-ray emission from Andromeda - a closer look
Christopher Eckner, Xian Hou, Pasquale D. Serpico +8
A new measurement of a spatially extended gamma-ray signal from the center of the Andromeda galaxy (M31) has been recently published by the Fermi-LAT collaboration, reporting that…
Gamma-ray emission from internal shocks in novae
Pierrick Martin, Guillaume Dubus, Pierre Jean +2
Gamma-ray emission at energies >100MeV has been detected from nine novae using the Fermi-LAT, and it can be explained by particle acceleration at shocks in these systems. Eight out…
Sizing up the population of gamma-ray binaries
Guillaume Dubus, Nicolas Guillard, Pierre-Olivier Petrucci +1
Gamma-ray binaries are thought to be composed of a young pulsar in orbit around a massive O or Be star, with their gamma-ray emission powered by pulsar spindown. The number of such…
