1 code implementation11 May 2021 Elena A. Kronberg, Tanveer Hannan, Jens Huthmacher, Marcus Münzer, Florian Peste, Ziyang Zhou, Max Berrendorf, Evgeniy Faerman, Fabio Gastaldello, Simona Ghizzardi, Philippe Escoubet, Stein Haaland, Artem Smirnov, Nithin Sivadas, Robert C. Allen, Andrea Tiengo, Raluca Ilie

The average correlation between the observed and predicted data is about 56%, which is reasonable in light of the complex dynamics of fast-moving energetic protons in the magnetosphere.

Joint Suzaku and Chandra observations of the MKW4 galaxy group out to the virial radius

no code implementations9 Dec 2020 Arnab Sarkar, Yuanyuan Su, Scott Randall, Fabio Gastaldello, Isabella Trierweiler, Raymond White, Ralph Kraft, Eric Miller

We measure an enclosed baryon fraction of 11% at R$_{200}$, remarkably smaller than the cosmic baryon fraction of 15%.

Analysis of the unconcentrated background of the EPIC-pn camera on board XMM-Newton

no code implementations3 Dec 2020 Martino Marelli, Silvano Molendi, Mariachiara Rossetti, Fabio Gastaldello, David Salvetti, Andrea De Luca, Iacopo Bartalucci, Patrick Kühl, Paolo Esposito, Simona Ghizzardi, Andrea Tiengo

Through this relationship we quantify the contribution of cosmic ray interactions to the pn unconcentrated background and we find a second source which contributes to the pn unconcentrated background for a significant fraction (30%-70%), that does not vary with time and is roughly isotropic.

Discovering the most elusive radio relic in the sky: Diffuse Shock Acceleration caught in the act?

no code implementations22 Apr 2020 Nicola T. Locatelli, Kamlesh Rajpurohit, Franco Vazza, Fabio Gastaldello, Daniele Dallacasa, Annalisa Bonafede, Mariachiara Rossetti, Chiara Stuardi, Etienne Bonassieux, Gianfranco Brunetti, Marcus Brüggen, Timothy Shimwell

The case of acceleration is challenged by the low predicted efficiency of low-Mach number merger shocks, unable to explain the power observed in most radio relics.
