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 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 ...

TDCOSMO: XVIII. Strong lens model and time-delay predictions for J1721+8842, the first Einstein zigzag lens

Frédéric Dux

We present lens models for J1721+8842, the first-ever discovered galaxy-scale strong lens in an Einstein zigzag configuration. The model consists of four separate lensed galaxies, with the primary source hosting a quasar, lensed into six images by two defl ...

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 ...

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

Michaela Hirschmann

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 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 ...

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 ...

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 ...

SPLEND1D, a reduced one-dimensional model to investigate the physics of plasma detachment

Christian Gabriel Theiler, Olivier Claude Martin Février, Sophie Danielle Angelica Gorno, Garance Hélène Salomé Durr-Legoupil-Nicoud, Massimo Carpita, Kim Dimuth Von Allmen

Studying the process of divertor detachment and the associated complex interplay of plasma dynamics and atomic physics processes is of utmost importance for future fusion reactors. While simplified analytical models exist to interpret the general features ...

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 ...

Fast dynamic 1D simulation of divertor plasmas with neural PDE surrogates

Yoeri Renier Johannes Poels

Managing divertor plasmas is crucial for operating reactor scale tokamak devices due to heat and particle flux constraints on the divertor target. Simulation is an important tool to understand and control these plasmas, however, for real-time applications ...

Self-consistent gyrokinetic modeling of turbulent and neoclassical tungsten transport in toroidally rotating plasmas

Kyungtak Lim

The effect of toroidal rotation on both turbulent and neoclassical transport of tungsten (W) in tokamaks is investigated using the flux-driven, global, nonlinear 5D gyrokinetic code GYSELA. Nonlinear simulations are carried out with different levels of mom ...
