Virgo Filaments. V. Disrupting the Baryon Cycle in the NGC 5364 Galaxy Group

Pascale Jablonka, Yannick Michael Bahé, Damien Louis Alexandre Spérone-Longin, Gautam Ramakrishnan Nagaraj

The Virgo Filament Survey (VFS) is a comprehensive study of galaxies that reside in the extended filamentary structures surrounding the Virgo Cluster, out to 12 virial radii. The primary goal is to characterize all of the dominant baryonic components withi ...

Characterising the z ≈ 7.66 Type-II AGN candidate SMACS S06355 using BEAGLE-AGN and JWST NIRSpec/NIRCam

Michaela Hirschmann, Adèle Marie Françoise Plat

The presence of Active Galactic Nuclei (AGN) in low mass (M⋆ ≲ 109 M⊙) galaxies at high redshift has been established, and it is important to characterise these objects and the impact of their feedback on the host galaxies. In this paper we apply the Spect ...

Comparing Compressed and Full-Modeling analyses with FOLPS: implications for DESI 2024 and beyond

Antoine Philippe Jacques Rocher

The Dark Energy Spectroscopic Instrument (DESI) will provide unprecedented information about the large-scale structure of our Universe. In this work, we study the robustness of the theoretical modelling of the power spectrum of FOLPS, a novel effective fie ...

Euclid V. The Flagship galaxy mock catalogue: A comprehensive simulation for the Euclid mission

Frédéric Courbin, Georges Meylan

We present the Flagship galaxy mock, a simulated catalogue of billions of galaxies designed to support the scientific exploitation of the Euclid mission. Euclid is a medium-class mission of the European Space Agency optimised to determine the properties of ...

BEAGLE-AGN I: simultaneous constraints on the properties of gas in star-forming and AGN narrow-line regions in galaxies

Michaela Hirschmann

We present the addition of nebular emission from the narrow-line regions (NLR) surrounding active galactic nuclei (AGNs) to BEAGLE (BayEsian Analysis of GaLaxy sEds). Using a set of idealized spectra, we fit to a set of observables (emission-line ratios an ...

The diverse star formation histories of early massive, quenched galaxies in modern galaxy formation simulations

Michaela Hirschmann

We present a comprehensive study of the star formation histories of massive-quenched galaxies at z = 3 in three semi-analytical models (SHARK, GAEA, GALFORM) and three cosmological hydrodynamical simulations (EAGLE, ILLUSTRISTNG, SIMBA). We study the predi ...

Euclid preparation XXXIII. Characterization of convolutional neural networks for the identification of galaxy-galaxy strong-lensing events

Frédéric Courbin, Georges Meylan, Georgios Vernardos, Benjamin Yvan Alexandre Clement

Forthcoming imaging surveys will increase the number of known galaxy-scale strong lenses by several orders of magnitude. For this to happen, images of billions of galaxies will have to be inspected to identify potential candidates. In this context, deep-le ...

Euclid preparation: XLII. A unified catalogue-level reanalysis of weak lensing by galaxy clusters in five imaging surveys

Frédéric Courbin, Georges Meylan, Austin Chandler Peel

Precise and accurate mass calibration is required to exploit galaxy clusters as astrophysical and cosmological probes in the Euclid era. Systematic errors in lensing signals by galaxy clusters can be empirically estimated by comparing different surveys wit ...

A luminous and young galaxy at z = 12.33 revealed by a JWST/MIRI detection of Hα and [O iii]

Michaela Hirschmann

The James Webb Space Telescope has discovered a surprising population of bright galaxies in the very early Universe (≲500 Myr after the Big Bang) that is hard to explain with conventional galaxy-formation models and whose physical properties are not fully ...

A detailed study of the very high-energy Crab pulsar emission with the LST-1

Andrii Neronov, Volodymyr Savchenko

Context. To date, three pulsars have been firmly detected by imaging atmospheric Cherenkov telescopes (IACTs). Two of them reached the TeV energy range, challenging models of very high-energy (VHE) emission in pulsars. More precise observations are needed ...

Identification of Spectral Distributions in Light-Dosimetry Data: Methodology and Application to an Intervention Field Study

Marilyne Andersen, Steffen Lutz Hartmeyer

Modern life in predominantly indoor environments has led to a profound alteration in the amount, spectral distribution, and pattern of light humans are exposed to daily. Given the role of light in health and well-being, and to understand how modern living ...

The Components of Cepheid Systems: The FN Vel System

Richard Irving Anderson, Giordano Viviani

Cepheid masses continue to be important tests of evolutionary tracks for intermediate-mass stars as well as important predictors of their future fate. For systems where the secondary is a B star, Hubble Space Telescope ultraviolet spectra have been obtaine ...

High-brightness transition metal-sensitized lanthanide near-infrared luminescent nanoparticles

Jean-Claude Bünzli

The demand for near-infrared (700–1,700 nm) materials in optical communications, laser sources and biological imaging applications has led to extensive research on lanthanide-doped nanoparticles, owing to their nanostructure modulation and interface proper ...
