We present the results of a near-infrared imaging study of the host galaxies of 17 quasars in the redshift range 1 RLQ(host)=-27.55+/-0.12 and K>RLQ(host)=-26...
The cosmic microwave background power spectrum out to l= 1400 measured by the Very Small Array
We have observed the cosmic microwave background (CMB) in three regions of sky using the Very Small Array (VSA) in an extended configuration with antennas of...
The cosmic waltz of Coma Berenices and Latyshev 2 (Group X). Membership, phase-space structure, mass, and energy distributions
Context. Open clusters (OCs) are fundamental benchmarks where theories of star formation and stellar evolution can be tested and validated. Coma Berenices (Coma...
The cosmic web connection to the dark matter halo distribution through gravity
This work investigates the connection between the cosmic web and the halo distribution through the gravitational potential at the field level. We combine three...
Context. Analysing the large-scale structure (LSS) in the Universe with galaxy surveys demands accurate structure formation models. Such models should ideally...
The Cosmological Optical Convergence: Extragalactic Background Light from TeV Gamma Rays
The intensity of the extragalactic background (EBL), the accumulated optical and infrared emissions since the first stars, is the subject of a decades-long...
The COSMOS-Web ring: In-depth characterization of an Einstein ring lensing system at z ∼ 2
Aims: We provide an in-depth analysis of the COSMOS-Web ring, an Einstein ring at z ≈ 2 that we serendipitously discovered during the data reduction of the...
The Counterjet of HH 30: New Light on Its Binary Driving Source
We present new [S II] images of the Herbig-Haro (HH) 30 jet and counterjet observed in 2006, 2007, and 2010 that, combined with previous data, allowed us to...
The coupled tearing-thermal instability in coronal current sheets from the linear to the non-linear stage
In the solar corona, magnetically sheared structures are unstable to both tearing and thermal instabilities in a coupled fashion. However, how the choice of...
