A number of challenges to the standard Λ CDM model have been emerging during the past
few years as the accuracy of cosmological observations improves. In this review we discuss …

Abstract Hyper Suprime-Cam (HSC) is a wide-field imaging camera on the prime focus of
the 8.2-m Subaru telescope on the summit of Mauna Kea in Hawaii. A team of scientists from …

Context. The AGN bolometric correction is a key element for understanding black hole (BH)
demographics and computing accurate BH accretion histories from AGN luminosities …

We combine results from deep ALMA observations of massive (M*> 10 10 M⊙) galaxies at
different redshifts to show that the column density of their interstellar medium (ISM) rapidly …

Aims. The eROSITA Final Equatorial-Depth Survey has been carried out during the
performance verification phase of the Spectrum-Roentgen-Gamma/eROSITA telescope and …

We present and characterize the catalog of galaxy shape measurements that will be used for
cosmological weak lensing measurements in the Wide layer of the first year of the Hyper …

Context. The eROSITA Final Equatorial Depth Survey (eFEDS), observed with eROSITA
ahead of its planned 4-yr all-sky survey, is the largest contiguous-field X-ray survey at …

Abstract The BAT AGN Spectroscopic Survey (BASS) is designed to provide a highly
complete census of the key physical parameters of the supermassive black holes (SMBHs) …

As matter accretes onto the central supermassive black holes in active galactic nuclei
(AGNs), X-rays are emitted. We present a population synthesis model that accounts for the …

Galaxy groups are more than an intermediate scale between clusters and halos hosting
individual galaxies, they are crucial laboratories capable of testing a range of astrophysics …
