How fast is the fastest-rotating O-type star in the Galaxy?
{Rapid rotation distorts massive stars, making parameters from spherical models inclination-dependent.Mock CSST NUV-NIR imaging of TNG50 galaxies with resolved stellar populations
We aim to develop a framework for producing CSST-like mock images of resolved stellar populations from simulated galaxies, demonstrated here using two TNG50 galaxies as illustrative test cases.The kinematic Kelvin-Helmholtz instability-driven dynamo: implications for merging compact objects
Binary neutron star (BNS) mergers excite a Kelvin--Helmholtz instability (KHI) in the shear layer between them.Spectroscopy-informed Deep Learning Searches for Photometric Little Red Dots in JWST Surveys
Little Red Dots (LRDs) are a population of compact, red sources discovered at high redshift with JWST that exhibit distinctive V-shaped spectral energy distributions (SEDs).Aperture-dependent [O III] profile variability: Clues to the nature of double-peaked narrow emission lines
We propose a simple and practical aperture-dependent method for investigating the physical origin of double-peaked narrow emission lines (DPNELs).Evolutionary Map of the Universe (EMU): Selection of active galactic nuclei and star-formation emission with machine-learning techniques
Sources detected by recent large-area radio surveys require robust classification and characterisation.A brief overview of the baryon cycle in galaxies
Galaxy formation and evolution is governed by the continuous exchange of gas between the cosmic web, the circumgalactic medium (CGM), and the interstellar medium (ISM) of galaxies.Quiescent galaxies at cosmic noon: from individual element abundances to star formation histories
Understanding the formation and early evolution of massive quiescent galaxies is crucial for a complete picture of galaxy formation in a cosmological context.Understanding galaxies and the origin of the golden mass through the study of scaling relations across cosmic history
The total mass distribution in galaxies strongly influences star formation (SF), both directly via gas availability and feedback, and indirectly via the dark matter (DM) potential well.Supermassive black holes and nuclear star clusters in galaxies: constraining formation and co-evolution with SHARP and MICADO
Nuclear star clusters and supermassive black holes are the dominant compact components in galaxy nuclei.The Environment of High-Energy Transient Host Galaxies at High Redshifts as Observed by SHARP
The study of transient events, such as Gamma-Ray Bursts (GRBs) and extreme Supernovae (SNe), provides a unique probe of star-forming environments in the early Universe.Net Cooling Tables for Cosmological Simulations under Multiple UV/X-ray Background Models
We present three sets of net cooling tables for cosmological hydrodynamical simulations, computed with CLOUDY 23.01 for optically thin gas in photoionization equilibrium with three different…AGN Host Galaxies in COSMOS-Web: Linking Structural Evolution and Star Formation Quenching up to $z=5$
The role of active galactic nuclei (AGNs) in the suppression of star formation and structural evolution of galaxies during their transition from star-forming to quiescent systems remains unclear.Gaia DR3 Reveals the Kinematics of Young Stellar Objects in the Carina Nebula: Peripheral Expansion and Central Rotation
We investigate the kinematics of the Carina Nebula using a sample of young stellar objects (YSOs) cross-matched with Gaia DR3, together with $^{12}\mathrm{CO}\,(1\mbox{--}0)$ molecular gas…Primary and Secondary Star Formation in the Spiral Waves of NGC 628
To determine the role of spiral arms and stellar feedback on the formation of stars, we examine the positions of optically identified and emerging star clusters in NGC 628.The dwarf galaxy NGC 185: the flagship of Andromeda's dwarf galaxies for the study of evolved multiple stellar populations
Reaching galaxies at 10-15 Mpc with HST and JWST requires star formation history (SFH) diagnostics that do not rely on the faint main sequence turn-off.Living near filaments: How environment shapes age profiles in low-mass galaxies
U-shaped radial age profiles have recently been reported in low-mass galaxies.Investigating the initial conditions of globular clusters via $N$-body simulations: I. half-mass radius and stellar density
Born out of the turbulent, dense gas of the early Universe, globular clusters (GCs) represent a significantly different star-formation mode compared to the local Universe.The formation and evolution of Wolf-Rayet stars with temperature-dependent winds
Massive stars strongly influence their environments through their radiation, stellar winds and core-collapse supernovae, while their own evolution is strongly shaped by wind mass loss.Euclid Quick Data Release (Q1). Refining the strong lens sample with Space Warps crowd-sourced science
We demonstrate the efficacy of crowd-sourced refinement of strong gravitational lens candidate samples by citizen scientists.
