Simulating winds in the Galactic centre. II. Observational biases on HI clouds and a multi-wavelength comparison
High-velocity neutral hydrogen (HI) clouds found up to several kiloparsecs above the Galactic centre (GC) provide some of the most direct evidence for a nuclear wind in the Milky Way, yet the…Boosted Physics-Informed Neural Networks for Solving Homogeneous and Non-Homogeneous Lane-Emden Type Equations
The Lane-Emden Equation is a class of nonlinear differential equations commonly used to model phenomena in astrophysics and mathematical physics, such as stellar structure and thermal behavior in…EMU/GAMA: Understanding the link between dust geometry and star formation rate in galaxies
We investigate the link between dust obscuration and star formation rate (SFR) estimators using Halpha luminosities, L_Halpha and radio luminosities, L_radio.Tracking the evolution of sub-Neptunes. I. Gyrochronology of planet hosting stars
Stellar age is fundamental for reconstructing planetary-system evolution but remains difficult to determine for unevolved main-sequence stars.Introducing Aurora: A New Black Hole Seeding Model With Explicit Environmental Coupling
We present Aurora, a black hole seeding module for the Mimic semi-analytic framework, in which the seed mass of each newly resolved halo is set by its environment.Witnessing pre-processing at intermediate redshift: observational evidence of infalling groups onto a merging galaxy cluster
The fraction of quenched galaxies increases with local density, and part of this trend is thought to arise in groups before cluster accretion (pre-processing).Stellar Bars Reshape the Spatial Distribution of UV-bright Clumps in Nearby Galaxies
Stellar bars redistribute gas and angular momentum in disk galaxies, but whether they mainly change the amount or the spatial organization of recent star formation remains uncertain.Kinematic Map of the Galactic Bulge Using HST Proper Motions
Constraining the Galactic bulge's non-axisymmetric dynamics requires proper motions in deep fields across many sightlines, yet crowding and extinction limit such measurements.Resolving the Complex Line-Locking Structure in Quasar J004613+010425 with VLT/X-shooter Spectroscopy
Line-locking (LL) signatures in quasar absorption-line systems provide direct observational evidence for radiatively driven outflows.OASIS I: Spectroscopy of Mini-Quenched and Lulling Galaxies Constrains the Quiet Side of Bursty Star Formation at z > 4
JWST has revealed that star formation in early galaxies is bursty, including episodes of violent suppression, so-called mini-quenching.OASIS II: The Ionized Gas Traces Feedback-Driven Declines into the Quiet Side of Bursty Star Formation at z > 4
Models of bursty star formation in low-mass (10^8-10^9.5 Msun) galaxies at z>4 differ most in the suppressed phases: what drives the decline, how fast star formation falls, and how long it stays low.OASIS III: Bursty star formation drives observed galaxy sizes at $z\geq4$
We employ JWST/NIRSpec MSA PRISM spectroscopy together with NIRCam imaging to investigate the impact of star-formation variability on galaxy sizes for a representative sample of 51 galaxies at…As a matter of reconstruction -- varying the magnetic Prandtl number in implicit large eddy simulations
The magnetic Prandtl number ($\mathrm{Pm}$), the ratio of viscosity to magnetic diffusivity, spans many orders of magnitude in astrophysical plasmas.Dark Halos, Intermediate-Mass BH and Nuclear Stellar Clusters in Dwarf Spheroidals
We exploit the halo densities of three dwarf spheroidals recently obtained to investigate their dark matter distribution.The JWST/PASSAGE Survey: Metallicity Radial Gradients in Emission-Line Galaxy Pairs at Cosmic Noon with NIRISS
Using JWST/NIRISS slitless spectroscopy from the PASSAGE program, we analyze 17 spectroscopically confirmed emission-line galaxies in candidate interacting systems at $z \sim 1.7$--$3.2$.Co-evolution of AGN and Host Galaxies across Cosmic Time Using JWST data
Understanding the complex co-evolution of active galactic nuclei (AGN) and their host galaxies across cosmic time remains a fundamental challenge, particularly in identifying how the physical…The Broad-Line Region Size-Luminosity Relation in AGN Constrained by the Viewing Angle with the FRADO Model
We investigate the H$β$ broad-line region (BLR) size-luminosity ($R_{\rm BLR}$-$L_{5100}$) relation of active galactic nuclei (AGN) using a Bayesian viewing angle inference framework based on the…The Evolution of the Circumgalactic Medium after a starburst in DESI Post-Starburst Galaxies
We present a statistical study of the cool circumgalactic medium (CGM) around massive post-starburst galaxies, traced by Mg II $λ\lambda2796,2803$ absorption in background quasar spectra from the…The Pristine Survey. XXX. Mapping substructures in the inner and outer halo with blue horizontal branch stars
Blue horizontal branch (BHB) stars serve as good standard candles and kinematic tracers of the Milky Way halo.The multiple origins of spurs in stellar streams: a challenge for dark matter diagnostics
Spurs along stellar streams are often interpreted as signatures of interactions with dark matter subhalos, and thus have been proposed as diagnostics on the clustering and nature of dark matter.
