Stacked strong and weak lensing united: Improved measurement of the stellar and dark matter distributions in massive early-type galaxies at $z\sim 0.5$
We present a new measurement of the stellar and dark matter distributions in massive early-type galaxies at redshift $0.4<z<0.6$ by combining stacked strong and weak lensing measurements.AGC 322753: a Dark Galaxy Candidate detected by ALFALFA and FASHI
We report the possible detection of a Dark Galaxy Candidate (DGC; AGC 322753), via the cross-matching of the Arecibo Legacy Fast ALFA (ALFALFA) and the FAST All Sky HI (FASHI) HI blind surveys.The impact of primordial magnetic fields on the formation of galaxies
Primordial magnetic fields (PMFs), potentially generated during cosmic inflation or early-universe phase transitions, can modify cosmic structure formation by enhancing the post-recombination matter…ArxSP: A Python-Based Modular Application for the Reduction of Digitized Archival Spectra
We present a methodology for the reduction of archival spectral data together with the description of a newly developed Python-based software package featuring an interactive graphical interface.Internal Structure, Not Environment, Shapes Metallicity Gradients in Low-Mass Galaxies from MaNGA
Dwarf and low-mass galaxies are highly sensitive to stellar feedback and gas flows, yet their spatially resolved gas-phase metallicity remains poorly characterised.Deep radio characterization of the supernova remnant G343.1-00.7
Supernova remnants (SNRs) are extended radio sources whose morphology and evolution are shaped by the interaction of strong shocks with the surrounding medium.High velocity dust grains produced by a supernova explosion
Motivated by the discovery of a meteor with velocity more than 300~km/s (Afanasiev et al. 2007) we study how dust grains formed in the supernova (SN) ejecta at its free-expansion phase can keep…Towards breaking the degeneracy between stellar ages and unresolved multiplicity
Stellar age is the central desirable parameter we need to disentangle different Galactic formation scenarios.High-Priority Compact-Object Candidates in Young Clusters from the \textit{Gaia} DR3 Non-Single-Star Catalog
The search for massive compact objects such as black holes (BHs) or neutron stars (NSs) in star clusters is longstanding challenge in astrophysics, yet no definitive identification of such compact…The role of velocity dispersion in the Kennicutt-Schmidt relation
The resolved Kennicutt-Schmidt (KS) relation is a power-law relation between the surface densities of the star formation rate ($Σ_\mathrm{SFR}$) and molecular gas ($Σ_\mathrm{mol}$) in star-forming…A New Sample of Closely Separated Dual and Binary AGN Candidates Revealed with the Radio Fundamental Catalog
The Big Multi-AGN Catalog (BigMAC) provides the first literature-complete compilation of confirmed and candidate dual, binary, and recoiling active galactic nuclei (AGN).Tracing star formation across the Rosette nebula using deep Spitzer imaging
We present a deep large-scale infrared survey of young stellar objects in the Rosette Nebula.When Streams Curve Away: a Test of Dark Matter from Extragalactic Stellar Stream Populations
The nature of dark matter sets the shape of galactic halos: collisionless cold dark matter (CDM) predicts triaxial halos, while scattering in self-interacting dark matter (SIDM) rounds them toward…The assembly history of NGC 1365 through chemical archaeology
Galaxies build through infalling gas and galaxy mergers.Sub-kiloparsec Test of the Kennicutt-Schmidt Relation in a Strongly Lensed Dusty Star-Forming Galaxy at z~2.78
[abridged] Star formation is a key process driving galaxy evolution, but understanding how it proceeds within the interstellar medium (ISM) requires resolving cold molecular gas and dust on sub-kpc…Probing the Reionization History and Bubble Sizes with JWST Lyman-$α$ Fraction Measurements
Recent James Webb Space Telescope (JWST) measurements quantify the fraction of ultraviolet-selected galaxies showing detectable Lyman-alpha (Ly-$α$) lines at $z \sim 6-14$.Water enhances the formation of refractory sulfur in interstellar ices
Sulfur is the tenth most abundant element in space, yet it is strongly depleted in the gas phase of dense interstellar regions, suggesting sequestration in dust grain components that are difficult…Gaia neutron stars: demographics, birth rates, and connections to other neutron star populations
Gaia DR3 revealed a new class of neutron stars (NSs) in au-scale orbits with solar-type companions.Which Milky Way Streams Make the Best Dark Matter Detectors?
The abundance and properties of low-mass dark matter subhalos can be inferred by measuring the density and velocity structure of stellar streams, testing physical models of dark matter.XClass: An Automated Multiwavelength Machine-Learning Pipeline for Classification of Extragalactic X-ray Sources. I. Pipeline Description
Most X-ray sources detected in nearby galaxies by the Chandra X-ray Observatory lack astrophysical classifications.
