The 10 Mpc Volume
Accurate distances are now known for most unobscured galaxies brighter than MB = -13 mag within 10 Mpc from Hubble Space Telescope observations of their luminous stars.Magnetic contribution to outer-disk rotation in the spiral galaxy NGC 5055
We test whether fields of galactic strength enhance NGC~5055's outer gas rotation.The Milky Way-like radial structure in nearby galaxies
The Milky Way exhibits a distinctive plateau in its inner surface brightness profile around one effective radius, challenging the traditional view of a purely exponential disk.Is Morphology All You Need? Quantifying Imprints of Past Star Formation in the Present-Day Morphologies of Galaxies
The next generation of galaxy surveys will bring a plethora of new observations, a vast majority of which will be observed with a few photometric broadbands, limiting the information we can infer…First Results from JACKS: A VLA Ammonia View of Gas Heating and Star-forming Cores in the Central Molecular Zone
The Central Molecular Zone (CMZ) combines warm molecular gas, strong turbulence, and a star-formation rate below that expected from its dense-gas reservoir.Confirming HSC strong lens candidates with DESI Spectroscopy. II. Analysis of 80 galaxy-scale systems with lens redshifts above 0.8
The total mass distribution of galaxies provides a sensitive probe of the fundamental physical processes governing galaxy evolution, including gas inflow/star formation, AGN/SN feedback, galaxy…Constraining the timescale of activity in Mrk 1018
We present analysis of an extended emission line region projected 3.77 kpc from the nucleus of the canonical changing-look AGN Mrk~1018, found in MUSE integral-field observations from the Close AGN…Violent relaxation in hierarchical stellar systems: pathways toward massive black hole formation in the early Universe
Massive stellar systems have been detected in the high-redshift Universe via the James Webb Space Telescope using gravitational lensing techniques.The Pristine survey XXXI. A stream offset from the Stream: very metal-poor stellar debris trailing 100$^{\circ}$ from the LMC-SMC system
The stellar counterpart to the $200^\circ$-long HI Stream from the Clouds probes their tidally stripped stellar populations and constrains their interaction history and structure before infall into…A Large-Sample Study of Interstellar Reddening in Galactic Star Clusters
The interstellar reddening (extinction or absorption) is caused mainly by the dust grains of different sizes and compounds.Multi-epoch monitoring of the faint northern component in 3C 84 during 2016-2021
We present the results of multi-epoch very long baseline interferometry (VLBI) observations of the sub-parsec-scale northern jet component of 3C 84 (known as the N1 component) at 7 mm from 2016 to…Cepheid Metallicity in the Leavitt Law (C-MetaLL) survey: X First spectroscopic characterization of Galactic Type II Cepheids and calibration of the Period-Wesenheit-Metallicity relations
Type II Cepheids (T2Cs) are Population II pulsating stars that serve as distance indicators through their period--luminosity relation.Multi-layer magnetic structure toward NGC 1333 revealed by a square-degree optical polarimetric survey
Magnetic-field studies of star-forming regions are complicated by overlapping structures along the line of sight.Survey of Surveys Data Release 3. Homogenised stellar parameters across nine spectroscopic surveys
Large spectroscopic surveys have measured atmospheric parameters for millions of Milky Way stars, but differences in instruments, wavelength ranges, analysis methods, and assumptions introduce…Octavius: A High-Performance Analysis Toolkit for Galaxy Simulations
Increased computing power and more efficient codes have allowed cosmological simulations of galaxy formation to grow massively in scale: the analysis of their outputs has consequently become a big…G92.4+5.0: A Perseus Arm superbubble associated with the H II region CTB 102
Superbubbles are vast hot cavities carved out by the stellar winds and supernovae of clusters of high-mass stars.Rotational Excitation of HC$_5$NH$^+$ by He: Collision Dynamics and Astrophysical Applications
Reliable collisional rate coefficients are crucial for interpreting the rotational emission spectra of molecules in interstellar clouds.Mitigating scanning-induced systematics in Hipparcos and implications for Gaia astrometry
Space-based astrometric missions such as Hipparcos and Gaia rely on one-dimensional scanning strategies that couple the measured signals with both observation times and scanning geometry.SDSS-V LVM: Spatial Resolution Effects on Diagnostic Diagrams in the Magellanic Clouds
We investigate how spatial resolution affects emission-line diagnostics in the interstellar medium (ISM) of the Small and Large Magellanic Clouds (SMC and LMC) using SDSS Local Volume Mapper (LVM)…The cold substellar frontier in JWST Extragalactic surveys: a robust parallax measurement yields the most distant known ultra-cold Y dwarf
We present an analysis of JADES-GS-BD-5, an extremely cold Y dwarf identified in the JADES/GOODS-South field.
