A -like metallicity profile in the disk of the Sagittarius dwarf galaxy
Zixi Guo, Xiang-Xiang Xue, Jiang Chang +12
Unveiling the properties of the progenitors that formed the tidal structures of the Milky Way (MW) is essential for exploring the MW's assembly history. Such studies further afford…
Identifying the principal mechanism of star formation feedback
Chong Li, Rouyu Li, Keping Qiu +27
Feedback from massive stars regulates the formation of next-generation stars and planets and thus shapes the evolution of galaxies, yet observational evidence capable of determinin…
High-Priority Compact-Object Candidates in Young Clusters from the \textit{Gaia} DR3 Non-Single-Star Catalog
Dejian Liu, Kangteng Chang, Yao Huang +7
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…
First Trigonometric Parallax Measurements with the KVN and VERA Array (KaVA)
Nobuyuki Sakai, Daisuke Sakai, Noriyuki Kawaguchi +26
To demonstrate the astrometric capability of the combined Korean VLBI (Very Long Baseline Interferometry) Network (KVN) and VLBI Exploration of Radio Astrometry (VERA) Array (KaVA)…
Supernova origin of galactic turbulence revealed by superbubbles
Fanyi Meng, Chao-Wei Tsai, Jingwen Wu +13
Supernovae (SNe) are among the leading candidates for powering galactic-scale turbulence. SNe drive expanding shells of neutral atomic hydrogen (HI) known as superbubbles. Due to t…
LenNet: Direct Detection and Localization of Strong Gravitational Lenses in Wide-Field Sky Survey Images
Pufan Liu, Hui Li, Ziqi Li +9
Strong gravitational lenses are invaluable tools for addressing fundamental questions in astrophysics, from the nature of dark matter to the expansion of the universe. While curren…
Local constraints on alcohol--thioalcohol analogs in G35.2N
Xuefang Xu, Shanghuo Li, Qian Gou +6
The chemistry of sulfur-bearing complex organic molecules in dense star-forming environments remains uncertain, partly because the dominant sulfur reservoirs in dense gas and ices…
Testing Chemical Tagging with LAMOST: Intrinsic Abundance Dispersion of Subgiant Stars in the Galactic Disk
Wu Yaqian, Xiang Maosheng, Zhao Gang +4
The scatter in elemental abundances among stars of similar age and metallicity reflects chemical inhomogeneity in their birth environments, making abundance scatter a key observabl…
ALMA Reveals an Explosive Outflow Candidate in IRAS 16119--5048
Yongquan Luo, Jianjun Zhou, Tie Liu +24
We present a multiwavelength study of the massive star formation region IRAS 16119-5048 (I16119) using ALMA ATOMS Band 3 and QUARKS Band 6 observations, complemented by archival AT…
An Eccentric Massive Protobinary Assembled via a Core-merger Parabolic Encounter
Yao Wang, Yichen Zhang, Rubén Fedriani +14
Most massive stars form in binary systems, which profoundly influence their subsequent evolution. However, how such systems form remains poorly understood, with several competing s…
SN 2021pfs: A Type Ia Supernova Likely Affected by Progenitor Metallicity, as Revealed by Comparison with Its Twin Counterpart
Abdusamatjan Iskandar, Xiaofeng Wang, Ali Esamdin +16
We present extensive photometric and spectroscopic observations of the normal type Ia supernovae (SNe Ia) 2021pfs, which occurred in the Seyfert 2 galaxy NGC 5427 at a redshift 0.0…
Infrared-excess sources in VVV: candidate debris discs, SED characterization, and variability analysis
P. Esteves, R. K. Saito, C. Chavero +9
Debris disks around main-sequence stars provide important insights into planetary formation and evolution; however, identifying these systems in the Galactic plane, where high inte…
TESS Observations of Seven Newly Identified High-amplitude Scuti Stars
Chenglong Lv, Ali Esamdin, Amir Hasanzadeh +3
We report seven newly identified high-amplitude Scuti (HADS) stars. Among them, two stars (TIC 30977864 and TIC 387379145) exhibit pure radial pulsation without the excitation…
A Population Study for Searching Supermassive Binary Black Holes in Active Galactic Nuclei: Continuum Spectral Features and Periodic Variabilities
Zekun Li, Changshuo Yan, Youjun Lu
Active sub-pc supermassive binary black holes (SMBBHs) are expected to exhibit various electromagnetic signatures due to unique dynamical and geometric structures of their accretio…
A Search for helium in the atmospheres of three sub-Neptunes and a super-Earth around M-dwarfs
Kiyoe Kawauchi, Norio Narita, Yuichi Ito +26
Thousands of sub-Neptunes have been discovered mainly through space-based surveys such as Kepler and TESS. Their bulk compositions and internal structures are thought to reflect th…
The mass-dependent interplay of active galacitc nuclei and supernova feedback in shaping the -- relation of early-type galaxies
Haojie Xia, Feng Yuan, Bocheng Zhu +4
The observed X-ray luminosity--temperature (--) relation of hot gas in early-type galaxies deviates significantly from the prediction of purely gravitational heating,…
Megaparsec-Scale Neutral Hydrogen Flows in the Neighborhood of Hickson Compact Group 100
Qingzheng Yu, Taotao Fang, Enrico M. Di Teodoro +2
The evolution of galaxies is strongly influenced by their ability to exchange gas with their surroundings, yet direct observational constraints on these processes remain scarce. Us…
