We conducted a study on the thermal properties of stellar matter with the nuclear energy density functional BCPM. This functionalis based on microscopic Brueckner–Hartree–Fock calculations and has demonstrated success in ...
The status of the Calar Alto Lunar Occultation Program is presented. This has been conducted at IR and optical wavelengths through OAN 1.5-m and CAHA 2.2-m telescopes, operating either with fast IR array or CCD. The ...
Motivated by gravitational-wave observations of binary neutron-star mergers, we study the thermal index of low-density, high-temperature dense matter. We use the virial expansion to account for nuclear interaction effects. ...
We study the decay J/ψ→π+π-π0 within the framework of the Khuri-Treiman equations. We find that the BESIII experimental dipion mass distribution in the ρ(770)-region is well reproduced with a once-subtracted P-wave amplitude. ...
Cherenkov Telescope Array Observatory (CTAO) is the next-generation ground-based <em>γ</em>-ray observatory operating in the energy range from 20GeV up to 300TeV, with two sites in La Palma (Spain) and Paranal (Chile). It ...
We present the current Standard Model (SM) prediction for the muon anomalous magnetic moment, aμ, updating the first White Paper (WP20) [1]. The pure QED and electroweak contributions have been further consolidated, while ...
Abstract Context. Hickson Compact Groups (HCGs) are dense gravitationally bound collections of four to ten galaxies and are ideal for studying gas and star formation quenching processes. Aims. We aim to understand the ...
This is the first paper in a series devoted to review the main properties of galaxies designated S0 in the Hubble classification system. Our aim is to gather abundant and, above all, robust information on the most relevant ...
We present the second study based on a suite of 100 cosmologically motivated, controlled N-body simulations designed to advance our understanding of the role of purely gravitational dynamics in the early formation of ...
Lenticular (S0) galaxies are ubiquitous in both high- and low-density environments where diverse evolutionary mechanisms operate. Consequently, studying their distribution and properties across both the dense, virialized ...
Utilizing the James Webb Space Telescope (JWST), the Atacama Large Millimeter/submillimeter Array (ALMA), and the Very Large Array (VLA), we present high angular resolution (0 06–0 42), multiwavelength (4 μm–3 cm) observations ...
ALMA-IMF observed 15 massive protoclusters capturing multiple spectral lines and the continuum emission. Here, we focus on the massive protocluster G351.77 (~2500 M⊙, estimated from single-dish continuum observations) ...
Context. Hydrogen recombination lines (HRLs) are valuable diagnostics of the physical conditions in ionized regions surrounding high-mass stars. Understanding these lines, including broadening mechanisms and intensity ...
We have observed the late Class I protostellar source Elias 29 at a spatial resolution of 70 au with the Atacama Large Millimeter/submillimeter Array as part of the FAUST Large Program. We focus on the line emission of SO, ...
[eng] In this thesis we have presented a new method to search for tidal streams generated by globular clusters in the Gaia catalogue. This statistical method is based on the maximum likelihood technique to distinguish ...
Stellar flares are powerful bursts of electromagnetic radiation triggered by magnetic reconnection in the chromosphere of stars, occurring frequently and intensely on active M dwarfs. While missions like TESS and Kepler ...
Single photon sources are fundamental for applications in quantum computing, secure communication, and sensing, as they enable the generation of individual photons and ensure strict control over photon number statistics. ...
We present the proof of concept of a method for finding strongly lensed quasars using their spatially extended photometric variability through difference imaging in cadenced imaging survey data. We applied the method to ...
Aims. As ground-based all-sky astronomical surveys will gather millions of images in the coming years, a critical requirement emerges for the development of fast deconvolution algorithms capable of efficiently improving ...
We present STARRED, a point-spread function (PSF) reconstruction, two-channel deconvolution, and light-curve extraction method designed for high-precision photometric measurements in imaging time series. An improved ...
