Competitive roles of turbulence and magnetic field on the formation of unipolar outflows in isolated molecular cloud cores
We investigate the impact of turbulence and magnetic field on the formation of unipolar outflows in the gravitational collapse of isolated low-mass cloud cores using three-dimensional non-ideal…The Central Molecular Zone of our Galaxy, a chemical complexity factory: first interstellar detections of molecules towards G+0.693
The Central Molecular Zone (CMZ) of our Galaxy is a prime laboratory for interstellar chemistry because of its extreme conditions, such as shocks and high cosmic-ray ionisation rates.The Milky Way's Early Disk Was Built in Bursts. I. Evidence from Low-angular-momentum, High-$α$ Stars Scattered Out of the Protodisk by Merger Events
Stars born in the high-$α$ disk can later acquire low angular momentum through dynamical scattering during early merger events.Star formation history of Draco revealed by DESI DR1: suppressed early star formation efficiency for Milky Way dwarf galaxies
Dwarf galaxies serve as fossils for understanding the early star formation history of the local Universe.The accretion flow and jet of M87: broadband modelling across spatial scales
The nearby radio galaxy M87 is an ideal laboratory for studying accretion flows and relativistic jet emission.PRISMS/U13151. A Glimpse into the Earliest Phases of Galaxy Formation through an Ultra-Faint System $\approx$ 500 Myr after the Big Bang
Detailed UV-to-optical studies of galaxies at z >= 10 have largely focused on bright systems (MUV <= -20 mag), leaving intrinsically faint galaxies virtually unexplored to date.Probing the Assembly of Triangulum: Precision Metallicities and $α$ Abundances of M33's Star Clusters from APOGEE Integrated-Light Spectroscopy
The star cluster system of M33 provides an excellent opportunity to investigate whether galaxy formation physics is dependent on a galaxy's mass.Extending the M33 Extinction Map with Radio and Far-Infrared Gas Observations
As the third-largest galaxy in the Local Group, M33 requires high-precision, wide-area extinction maps to recover the intrinsic luminosity and enable accurate studies, yet the available maps remain…ERGO-ML and how to directly infer the multi-temperature nature of intra-cluster gas: simulation-based inference with TNG-Cluster
Though galaxy clusters are virialized and mostly in thermodynamic equilibrium, their internal gas thermodynamics are complex.Low-mass and High-sSFR H$α$ Emitters at $z \sim 2$ in the ZFOURGE-COSMOS Field
We present a near-infrared spectroscopic follow-up study of seven H$α$ emitter candidates at $z\sim2$ in the ZFOURGE-COSMOS field, selected via the $K_{\rm s}$-band flux excess method.PSR~B0355+54: An Unexpected Compendium of Nearly All Scintillation Arc Morphologies
Scintillation arcs are sensitive probes of multipath propagation, offering a window into the distribution of scattering material in the interstellar medium.Graph Neural Networks for Astrophysics and Cosmology
Physics seldom makes breakthroughs when we consider objects only in isolation.The ALMA REBELS Survey: The [C II] Luminosity Function of UV-Selected Galaxies at $z\sim7$
Luminosity functions (LF) are some of the most basic quantities providing insights into galaxy evolution across cosmic time and enabling a direct comparison between observations and simulations.Annihilation feedback on elastic scattering in self-interacting dark matter
Sizable dark-matter self-interactions, motivated by observations of galactic structure, often arise from the exchange of light force mediators.How does a galaxy's quenching probability depend on its black hole's mass?
We develop a parametric toy model to explore how black hole mass scatter $σ_{\rm BH}$ and the dependence of the quenching probability per unit time on black hole mass, parameterized as a power law…Metal-poor molecular clouds in dwarf galaxies at parsec-scale resolution
Understanding how stars form at low metallicity is challenging because carbon monoxide (CO) emission, which usually probes the molecular gas reservoir, is faint, and tends to be concentrated in…Optical and Ultraviolet Emission from the Gas Photoionized by Gaia BH3: Archival Constraints and Predictions for the 2029 Periastron
Gaia BH3, a $32.7\,M_\odot$ black hole (BH) on an 11.6-yr, $e=0.73$ orbit around a metal-poor giant at $\approx590$ pc, accretes from its wind.Balmer breaks in accreting super-massive black hole binaries
We show that truncated circumbinary accretion disks around super-massive black hole binaries can produce Balmer breaks.Dual and lensed AGN at sub-arcsecond separations uncovered by ERIS
We present the first results of the ongoing INAF GTO program focused on the search of sub-arcsecond dual AGN, carried out with the near-infrared integral-field unit SPIFFIER of the Enhanced…Self-interacting dark matter from radiative bound-state-formation feedback
Observations of galactic structure motivate sizable dark-matter self-interactions at low velocities, naturally realized through light force mediators.
