Supermassive Black Hole Winds in X-rays -- SUBWAYS. VI. Interplay between the soft X-ray excess and ultra-fast outflows

V. E. Gianolli, P-O. Petrucci, S. Bianchi +42

We present a broadband, multiwavelength study of the interplay between the soft X-ray excess (SE), ultra-fast outflows (UFOs), and warm absorbers (WAs) in 21 active galactic nuclei…

Precise QCD Predictions for the Scotogenic Model at Colliders

Mohammed Boukidi, Camila Ramos, Richard Ruiz

Motivated by the anticipated data rates of the high-luminosity phase of the Large Hadron Collider, we report the first predictions up to next-to-leading order in quantum chromodyna…

Euclid: Quick Data Release (Q1) -- Optical hotspots in powerful radio galaxies

M. J. Hardcastle, L. Bisigello, M. Bondi +154

The hotspots of powerful radio galaxies are the sites of high-energy particle acceleration, but radio observations give us limited information on the electron energy distributions…

The Next Generation Virgo Cluster Survey (NGVS). II. A Catalog of Galaxies in the Virgo Cluster

Laura Ferrarese, Patrick Cote, Lauren A. MacArthur +51

The Next Generation Virgo Cluster Survey (NGVS) is a deep, high resolution imaging campaign that used the 1 deg MegaCam instrument on the Canada-France-Hawaii Telescope to carr…

Euclid: The convective-transition gap of 47 Tuc

M. Libralato, M. Griggio, R. Gerasimov +140

We report the first detection of the `convective-transition gap' (also known as `M-dwarf gap') in the globular cluster 47 Tuc (NGC 104) thanks to Euclid data. This feature, linked…

Early Light Curve Excess in Type IIb Supernovae Observed by the ATLAS Survey: Qualitative Constraints on Progenitor Systems

Bastian Ayala, Joseph P. Anderson, G. Pignata +8

Type IIb supernovae (SNe IIb) often exhibit an early light curve excess (EE) preceding the main peak powered by radioactive nickel decay. The physical origin of this early emission…

Variability in low Mars atmosphere's HO concentration stimulated by solar cycle activity

Johan Nicolás Molina Córdoba, S. Vargas Domínguez, J. I. Zuluaga

Mars' thin, CO-rich atmosphere poses a unique puzzle involving composition, climate history, and habitability. This work explores the intrincate relationship between Mars' atmo…

The temporal evolution of gas accretion onto the discs of simulated Milky Way-mass galaxies

F. G. Iza, S. E. Nuza, C. Scannapieco

In the standard model of structure formation, galaxies form in the centre of dark matter haloes that develop as a result of inhomogeneities in the primordial mass distribution of t…

Stellar collisions in globular clusters: the origin of multiple stellar populations

Valery Kravtsov, Sami Dib, Francisco A. Calderon +1

Two generations of stars, G1 and G2, typically populate Galactic globular clusters (GCs). The origin of G2 stars is unclear. We uncover two empirical dependencies between GC charac…

The baryonic mass assembly of low-mass halos in a Lambda-CDM Universe

Maria E. De Rossi, Vladimir Avila-Reese, Patricia B. Tissera +2

We analyse the dark, gas, and stellar mass assembly histories of low-mass halos (Mvir ~ 10^10.3 - 10^12.3 M_sun) identified at redshift z = 0 in cosmological numerical simulations.…

Downsizing of galaxies vs upsizing of dark-halos in a Lambda-CDM cosmology

Maria E. De Rossi, Vladimir Avila-Reese, Alejandro Gonzalez-Samaniego +1

The mass assembly of a whole population of sub-Milky Way galaxies is studied by means of hydrodynamical simulations within the -CDM cosmology. Our results show that while dark h…

A Survey of Astronomical Research: An Astronomy for Development Baseline

V. A. R. M. Ribeiro, P. Russo, A. Cardenas-Avendano

Measuring scientific development is a difficult task. Different metrics have been put forward to evaluate scientific development; in this paper we explore a metric that uses the nu…
