Probing Multi-formation Channels of Dark Matter-Deficient Galaxies in a Simulated Universe
We investigate the formation and evolution of dark matter-deficient galaxies (DMDGs) using the IllustrisTNG100 cosmological hydrodynamical simulation.The Peculiar Astrometric Behaviour and Radio Structure of the Quasar 1524-136 Revealed with Very Long Baseline Interferometry
According to astrometric very long baseline interferometry (VLBI) observations accurate to sub-milliarcsecond levels, the radio quasar 1524-136 (J1526-1351) exhibited an exceptionally large shift…Hoag-type Galaxies: A Photometric Study of the Cores and Rings of Thirty Systems from the DESI Legacy Survey
Hoag-type galaxies contain a smooth central core surrounded by a detached outer ring, but their rarity has limited previous studies mainly to individual systems.Detection of HNCOH+ in the interstellar medium
Only five out of the $\sim$350 molecules detected in the interstellar medium (ISM) carry the isocyanate functional group (NCO), the essential substructure of peptide bonds in proteins.Dust growth in the early Universe: insight from the NewCluster spin-off simulation
We investigate dust evolution in galaxies at $z\sim5$ using a spin-off run of the \NC\ cosmological zoom-in simulation with a live two-species, two-size dust model.Feeding or Fleeing: The Impact of Enhanced Early Black Hole Growth on Circumgalactic Clumps at $z > 6$
The circumgalactic medium (CGM) of massive high-redshift galaxies contains inflowing filamentary gas, recycled material, and feedback-driven outflows.The stellar orbit distribution of 24 late-type galaxies observed by MUSE
We selected 24 nearby late-type galaxies from the MUSE archive with kinematic coverage extending to at least one effective radius.A MUSE and MeerKAT study of dynamics and star formation in HCG 16
Hickson Compact Groups (HCGs) present an ideal environment for studying galaxy interactions.Mapping cluster angular momentum with the rotational kinetic Sunyaev-Zel'dovich effect
Galaxy clusters carry angular momentum.Channelled versus Isotropic Accretion of Galaxy Groups onto Clusters: Kinematics, Spin Alignment, and Assembly Bias
Galaxy clusters grow by accreting groups from the cosmic web, but whether the route of infall (along a cluster-connected filament or from the open field) imprints a group's kinematics, spin, and…Four-hundred Very Metal-poor Stars Studied with LAMOST and Subaru. IV. Heavy Element Enhanced Stars
We perform a homogeneous analysis of 82 heavy-element-enhanced metal-poor stars from the\\ LAMOST/Subaru sample, including 64 $r$-process-enhanced stars, 2 limited-$r$ stars, and 16 stars exhibiting…SDSS-V LVM: Mapping of plasma temperatures in the Lagoon Nebula reveals the origin of long-standing chemical abundance discrepancies
Knowing the chemical composition of interstellar gas is essential for understanding the chemical evolution of galaxies.Can the $\sim 5$ kpc starburst ring in MW create eROSITA bubbles?
eROSITA bubbles (eRBs) in our Galaxy are thought to be due to the energy injection by the central star-forming region or the central Super Massive Black Hole.Extracting non-Gaussian information of line-intensity maps with weighted skew spectra
The bispectrum of line-intensity maps carries cosmological and astrophysical information beyond the power spectrum, but its large data vector hampers the analysis of survey data.What kinds of strong star--black-hole encounters in AGN disks occur, and how often?
Disks surrounding active galactic nuclei contain many stars and black holes, which will inevitably encounter one another.Celia: Catalog Embeddings Learned from cosmologIcal simulAtions
Cosmological hydrodynamical simulations connect observed galaxies to cosmology and the physics of galaxy formation.A compact NH$_2$D source without NH$_3$ counterpart in the S187 high-mass star-forming region
Our goal is to investigate a so far only tentatively detected compact NH$_2$D source devoid of a notable NH$_3$ counterpart, located rather close to the luminous IRAS 01202+6133 source (the…Toward a Complete Interpretation of Global 21 cm Absorption Signals Using the Radio CMB
The global 21 cm signal is among the most direct probes of cosmic dawn, encoding information about when the first stars formed and how efficiently they heated their surroundings.Playing CHESS with stars II. Homogeneous analysis of high-resolution optical spectra for a sample of 135 giants in 14 bulge globular clusters
Bulge globular clusters are key tracers of the complex formation history of the Galactic bulge, as they retain information on its past star-formation episodes.Complex Organic Molecules in Protostars with ALMA Spectral Surveys (COMPASS) VIII. First interstellar detection of fully deuterated methyl cyanide
Deuteration is a powerful metric to gain insight into the formation pathways of interstellar molecules in star forming regions.
