A Relationship Between Fast Radio Burst Dispersion Measure and Host Galaxy Inclination
It is commonly thought that fast radio bursts (FRBs) trace star formation, and that they are produced by magnetars.Where Cluster Galaxies Reside and How Strongly They Lens
The efficiency of galaxy-galaxy strong lensing (GGSL) in clusters depends jointly on the inner mass distributions of member galaxies and their locations within the cluster potential.Galaxy Clustering Can Reveal Host-Galaxy Properties of Binary Black Hole Mergers
Galaxy clustering encodes information about the host galaxies of binary black hole (BBH) mergers even when individual hosts remain unidentified, because the distribution of neighboring galaxies…Too many or too bright? Status and perspectives in the study of the UV Luminosity Function at z>10
The finding that galaxies in the first 500Myr were much more numerous and/or brighter than expected is often cited as one of the main discoveries of the James Webb Space Telescope in its first four…Modeling CO Line Luminosity Using FIRE Simulations: I. Methodology and Validation of Molecular Gas and CO Abundance
We present a post-processing pipeline that predicts CO line luminosities, molecular hydrogen masses, and CO abundances for galaxies in the Feedback in Realistic Environments (FIRE-2) simulations, as…Mass Proxy Quality of Halo Properties in IllustrisTNG and FLAMINGO Simulations: II. Galaxies, Stars, and Black Holes
We study the stellar, black hole, and satellite galaxy populations of group- and cluster-scale halos in the IllustrisTNG, TNG-Cluster, and FLAMINGO cosmological hydrodynamical simulations.The conditional colour-magnitude distribution: III. A study of galaxy colour- and luminosity-dependent counts-in-cells statistics
The conditional colour-magnitude distribution (CCMD) model connects the galaxy colour-luminosity distribution with dark matter halo mass, which has been constrained in Xu et al. by jointly modelling…Chaotic accretion can (still) explain early supermassive black hole growth
The origin of supermassive black holes (SMBHs) is still debated, with hypotheses ranging from massive seeds to super-Eddington growth to chaotic accretion.ApPolLO: Apertif counterparts of Polarised LOFAR sources
Knowledge of the structure and evolution of cosmic magnetic fields is indispensable to understand how primordial magnetic fields were generated and amplified during the lifetime of the Universe.The impact of feedback and cosmology on Cosmic Infrared Background cross-correlations
We study the evolution and clustering properties of the star formation rate density (SFR) $ρ_{\rm SFR}$ in the FLAMINGO suite of hydrodynamical simulations, with the aim of exploring the possibility…Halo Mass Function Constraints on Early Galaxy and AGN Populations in the JWST Era
The discovery by the James Webb Space Telescope (JWST) of massive galaxies and luminous active galactic nuclei (AGN) at high redshift provides an increasingly sensitive test of the connection…Convergence of Roberts flow dynamos in Eulerian and Lagrangian codes
Standard benchmark tests for numerical magnetohydrodynamics codes focus on one- and two-dimensional problems that ignore the possibility of dynamos, i.e., an exponential instability converting…The star-forming past and quenching of brightest cluster galaxies in TNG-Cluster
The Brightest Cluster Galaxies (BCGs) in the most massive galaxy clusters of our Universe are, at present, mostly quiescent, elliptical, and red.Disentangling the assembly of the central and diffuse stellar components in galaxy clusters through dynamical friction and tidal stripping
In galaxy clusters, it is common to conceptually distinguish the central, brightest cluster galaxy (BCG) from the more diffuse intracluster light (ICL).EMIR confirmation of the high-z Lyα blob SHARDS20018464
A spectroscopic follow-up of the Ly$α$ blob SHARDS20018464 was performed using the infrared spectrograph EMIR (Espectrógrafo Multiobjeto Infra-Rojo) at the 10.4 m GTC telescope, equipped with its…And Then There WEre Baryons (ATWEB): The Baryon Budget of the Universe in Halos and the IGM over 13 Billion Years of Cosmic Time
Observations of the local Universe show that, except in the most massive galaxy clusters, the baryon fraction within halos falls below the cosmic mean.Hierarchical Black Hole Mergers at High Redshift: Predictions for LISA and LGWA from SEEDZ
We investigate the hierarchical assembly of black holes (BHs) in the early Universe using the next-generation SEEDZ cosmological zoom-in simulations.A Brush with Turbulence: Probing the ICM Dynamics in the Merging Toothbrush Cluster using XRISM
The Toothbrush Cluster (1RXS J0603.3+4214) is known for its northern radio relic, radio halo, and highly disturbed X-ray morphology.Baryonic Imprints on DM Halos: the concentration-mass relation and its dependence on 28 model parameters in the CAMELS suite
The evolution of baryons in halos, as well as their gravitational impact on the total-matter phase space, has a rich phenomenology and is vital in answering many questions in both cosmology and…Comment on ''Chiral electromagnetic surface waves on Chern-Simons interfaces'' Phys.Rev.D114(2026)L051903 and on arXiv:2606.12513 by N. Kaloper
We demonstrate that Maxwell electrodynamics interacting with a planar Chern-Simons interface does not have plane wave solutions localized on the interface.
