Euclid: Early Release Observations of diffuse stellar structures and globular clusters as probes of the mass assembly of galaxies in the Dorado group?

Deep surveys have helped to unveil the history of past and present galaxy mergers, and, in particular, uncovering their tidal debris and co-located globular clusters (GCs). Euclid’s unique combination of capabilities (spatial resolution, depth, and wide sk ...

The AGORA High-Resolution Galaxy Simulations Comparison Project VII. Satellite quenching in zoom-in simulation of a Milky Way-mass halo

Yves Revaz

Context. Satellite galaxies experience multiple physical processes when interacting with their host halos, often leading to the quenching of star formation. In the Local Group, satellite quenching has been shown to be highly efficient, affecting nearly all ...

Evidence for a Shallow Evolution in the Volume Densities of Massive Galaxies at z = 4-8 from CEERS

Michaela Hirschmann

We analyze the evolution of massive (log10[M ⋆/M ⊙] > 10) galaxies at z ∼ 4-8 selected from JWST Cosmic Evolution Early Release Survey (CEERS). We infer the physical properties of all galaxies in the CEERS NIRCam imaging through spectral energy distributio ...

IFUM integrated field spectroscopy of ten M104 satellite galaxy candidates

Oliver Müller

We report the spectroscopic analysis of 10 satellite galaxy candidates in the sphere of influence of the Sombrero galaxy (M104, NGC4594), based on data obtained with IFUM (integral field units for Magellan). Based on their newly observed recessional veloci ...

Resolved UV and Optical Color Gradients Reveal Environmental Influence on Galaxy Evolution at Redshift z ∼ 1.6

Yannick Michael Bahé

The changes in colors across a galaxy are intimately connected to the galaxy’s formation, growth, quenching history, and dust content. A particularly important epoch in the growth of galaxies is near z ∼ 2, often referred to as “cosmic noon,” where galaxie ...

On the origin of globular clusters in a hierarchical universe

Michaela Hirschmann

We present an end-to-end description of the formation of globular clusters (GCs) combining a treatment for their formation and dynamical evolution within galaxy haloes with a state-of-the-art semi-analytic simulation of galaxy formation. Our approach allow ...

Efficient NIRCam Selection of Quiescent Galaxies at 3 < z < 6 in CEERS

Michaela Hirschmann

Substantial populations of massive quiescent galaxies at z ≥ 3 challenge our understanding of rapid galaxy growth and quenching over short timescales. In order to piece together this evolutionary puzzle, more statistical samples of these objects are requir ...

Strong gravitational lensing by AGNs as a probe of the quasar-host relations in the distant Universe

Frédéric Courbin, Malte Tewes, Martin Raoul Robert Millon, Aymeric Alexandre Galan

A rare case of a quasar acting as a gravitational lens allows a precise determination of the mass of the quasar's host galaxy and offers a new path to studying the connections between supermassive black holes and their host galaxies. ...

The contribution of magnetized galactic outflows to extragalactic Faraday rotation

Andrii Neronov

Galactic outflows driven by star formation and active galactic nuclei blow bubbles into their local environments, causing galactic magnetic fields to be carried into intergalactic space. We explore the redshift-dependent effect of these magnetized bubbles ...

Magnetic fields do not suppress global star formation in low metallicity dwarf galaxies

Robin Gopala Tress

Many studies concluded that magnetic fields suppress star formation in molecular clouds and Milky Way like galaxies. Ho we ver, most of these studies are based on fully developed fields that have reached the saturation level, with little work on investigat ...
