The Rise of Faint, Red Active Galactic Nuclei at z > 4: a Sample of Little Red Dots in the Jwst Extragalactic Legacy Fields

We present a sample of 341 "little red dots" (LRDs) spanning the redshift range z similar to 2-11 using data from the CEERS, PRIMER, JADES, UNCOVER, and NGDEEP surveys. Unlike past use of color indices to identify LRDs, we employ continuum slope fitting us ...

The Galaxy Activity, Torus, and Outflow Survey (GATOS) VI. Black hole mass estimation using machine learning

Rémi Henri Philippe Poitevineau

The detailed feeding and feedback mechanisms of active galactic nuclei (AGNs) are not yet well known. For low-luminosity AGNs, obscured AGNs, and late-type galaxies, the masses of their central black holes (BH) are difficult to determine precisely. Our goa ...

The Impact of Cosmic Ray Feedback During the Epoch of Reionisation

Marion Nancy Amandine Farcy

Galaxies form and evolve via a multitude of complex physics. In this work, we investigate the role of cosmic ray (CR) feedback in galaxy evolution and reionisation, by examining its impact on the escape of ionising radiation from galaxies. For this purpose ...

Euclid: Early Release Observations - A glance at free-floating newborn planets in the σ Orionis cluster

Frédéric Courbin, Georges Meylan

We provide an early assessment of the imaging capabilities of the Euclid space mission to deeply probe nearby star-forming regions and associated very young open clusters, and in particular, to determine to which extent it can shed light into the newborn f ...

The Impact of Ram Pressure on Cluster Galaxies, Insights From Gaea and Tng

Michaela Hirschmann

Ram pressure stripping (RPS) has a non-negligible impact on the gas content of cluster galaxies. We used the semi-analytic model GAEA and the hydro-simulation TNG to investigate whether cluster galaxies suffer from strong RPS that is sufficient to remove a ...

3d Cmz. II. Hierarchical Structure Analysis of the Central Molecular Zone

Robin Gopala Tress

The Central Molecular Zone (CMZ) is the way station at the heart of our Milky Way Galaxy, connecting gas flowing in from Galactic scales with the central nucleus. Key open questions remain about its 3D structure, star formation properties, and role in regu ...

Lopsided distribution of MATLAS and ELVES dwarf satellite systems around isolated host galaxies

Oliver Müller, Nick Heesters

The properties of satellite dwarf galaxies provide important empirical insights for verifying cosmological models on galaxy scales. Their phase-space correlations, in particular, offer interesting insights into a broad range of models, since they are domin ...

Strong lensing by edge-on galaxies in UNIONS

Frédéric Courbin, Cameron Alexander Campbell Lemon, Elodie Marie Charlène Savary, Javier Alejandro Acevedo Barroso

Current searches for galaxy-scale strong lenses focus on massive Luminous Red Galaxies but tend to overlook late-type lenses, in part because of their smaller Einstein radii. We take advantage of the superb seeing of the UNIONS survey in the r-band to perf ...

JWST lensed quasar dark matter survey – I. Description and first results

Cameron Alexander Campbell Lemon

All rights reserved.The flux ratios of gravitationally lensed quasars provide a powerful probe of the nature of dark matter. Importantly, these ratios are sensitive to small-scale structure, irrespective of the presence of baryons. This sensitivity may all ...

Search for dark QCD with emerging jets in proton-proton collisions at √s=13 TeV

Jan Steggemann, Konstantin Androsov, Anna Mascellani, Joanna Malgorzata Wanczyk

A search for "emerging jets" produced in proton-proton collisions at a center-of-mass energy of 13 TeV is performed using data collected by the CMS experiment corresponding to an integrated luminosity of 138 fb(-1). This search examines a hypothetical dark ...
