Probing the full CO spectral line energy distribution (SLED) in the nuclear region of a quasar-starburst system at
Jianan Li, Ran Wang, Dominik Riechers +14
We report Atacama Large Millimeter/submillimeter Array (ALMA) observations of CO , , and and NOrthern Extend…
NuSTAR/XMM-Newton monitoring of the Seyfert 1 galaxy HE 1143-1810. Testing the two-corona scenario
F. Ursini, P. -O. Petrucci, S. Bianchi +11
We test the two-corona accretion scenario for active galactic nuclei in the case of the `bare' Seyfert 1 galaxy HE 1143-1810. We perform a detailed study of the broad-band UV--X-ra…
Localizing the -ray emitting region in the blazar TXS 2013+370
E. Traianou, T. P. Krichbaum, B. Boccardi +9
The -ray production mechanism and its localization in blazars are still a matter of debate. The main goal of this paper is to constrain the location of the high-energy emission…
XXL Survey groups and clusters in the Hyper Suprime-Cam Survey. Scaling relations between X-ray properties and weak lensing mass
Mauro Sereno, Keiichi Umetsu, Stefano Ettori +13
Scaling relations trace the formation and evolution of galaxy clusters. We exploited multi-wavelength surveys -- the XXL survey at \emph{XMM-Newton} in the X-ray band, and the Hype…
Helium abundance (and ) in X-COP galaxy clusters
S. Ettori, V. Ghirardini, D. Eckert
We present the constraints on the helium abundance in 12 X-ray luminous galaxy clusters that have been mapped in their X-ray and Sunyaev-Zeldovich (SZ) signals out to for…
Non-linear damping of superimposed primordial oscillations on the matter power spectrum in galaxy surveys
Mario Ballardini, Riccardo Murgia, Marco Baldi +2
Galaxy surveys are an important probe for superimposed oscillations on the primordial power spectrum of curvature perturbations, which are predicted in several theoretical models o…
