Chasing Gravitational Waves with the Cherenkov Telescope Array

Jarred Gershon Green, Alessandro Carosi, Lara Nava +563

The detection of gravitational waves from a binary neutron star merger by Advanced LIGO and Advanced Virgo (GW170817), along with the discovery of the electromagnetic counterparts…

Interpolation of Instrument Response Functions for the Cherenkov Telescope Array in the Context of pyirf

Rune Michael Dominik, Maximilian Linhoff, Julian Sitarek

The Cherenkov Telescope Array (CTA) will be the next generation ground-based very-high-energy gamma-ray observatory, constituted by tens of Imaging Atmospheric Cherenkov Telescopes…

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…

Breaking the Chains: Hot Super-Earth systems from migration and disruption of compact resonant chains

Andre Izidoro, Masahiro Ogihara, Sean N. Raymond +5

"Hot super-Earths" (or "Mini-Neptunes") between 1 and 4 times Earth's size with period shorter than 100 days orbit 30-50\% of Sun-like type stars. Their orbital configuration -- me…

Hot super-Earths and giant planet cores from different migration histories

Christophe Cossou, Sean N. Raymond, Franck Hersant +1

Planetary embryos embedded in gaseous protoplanetary disks undergo Type I orbital migration. Migration can be inward or outward depending on the local disk properties but, in gener…

The fast C(3P) + CH3OH reaction as an efficient loss process for gas-phase interstellar methanol

Robin J. Shannon, Christophe Cossou, Jean-Christophe Loison +5

Rate constants for the C(3P) + CH3OH reaction have been measured in a continuous supersonic flow reactor over the range 50 K to 296 K. C(3P) was created by the in-situ pulsed laser…

No universal minimum-mass extrasolar nebula: Evidence against in-situ accretion of systems of hot super-Earths

Sean N. Raymond, Christophe Cossou

It has been proposed that the observed systems of hot super-Earths formed in situ from high-mass disks. By fitting a disk profile to the entire population of Kepler planet candidat…

Making giant planet cores: convergent migration and growth of planetary embryos in non-isothermal discs

Arnaud Pierens, Christophe Cossou, Sean Raymond

Earth-mass bodies are expected to undergo Type I migration directed either inward or outward depending on the thermodynamical state of the protoplanetary disc. Zones of convergent…

Making systems of Super Earths by inward migration of planetary embryos

Christophe Cossou, Sean N. Raymond, Arnaud Pierens

Using N-body simulations with planet-disk interactions, we present a mechanism capable of forming compact systems of hot super Earths such as Kepler 11. Recent studies show that ou…

Convergence zones for Type I migration: an inward shift for multiple planet systems

Christophe Cossou, Sean Raymond, Arnaud Pierens

Earth-mass planets embedded in gaseous protoplanetary disks undergo Type I orbital migration. In radiative disks an additional component of the corotation torque scaling with the e…

Primary and secondary eclipse spectroscopy with JWST: exploring the exoplanet parameter space

A. R. Belu, F. Selsis, J-C. Morales +3

Eclipse exoplanet spectroscopy has yielded detection of H_2O, CH_4, CO_2 and CO in the atmosphere of hot jupiters and neptunes. About 40 large terrestrial planets are announced or…
