Milliarcsecond-scale radio structure of the most distant BL Lac object candidate at redshift 6.57
S. Frey, Y. Zhang, K. Perger +7
The existence of accreting supermassive black holes up to billions of solar masses at early cosmological epochs (in the context of this work, redshifts z>=6) requires very fast gro…
Observational Evidence of a Centi-parsec Supermassive Black Hole Binary Existing in the Nearby Galaxy M81
Wu Jiang, Zhiqiang Shen, Ivan Martí-Vidal +6
Studying a centi-parsec supermassive black hole binary (SMBHB) would allow us to explore a new parameter space in active galactic nuclei, and these objects are also potential sourc…
Unveiling Luminous Ly Emitters at through JWST/NIRCam Imaging in the COSMOS Field

To understand the relation between NHD and its physical environment, we mapped ortho-NHD at 85.9 GHz toward 24 Galactic late-stage massive star-forming…
An evolutionary continuum from nucleated dwarf galaxies to star clusters
Kaixiang Wang, Eric W. Peng, Chengze Liu +21
Systematic studies have revealed hundreds of ultra-compact dwarf galaxies (UCDs) in the nearby Universe. With half-light radii of approximately 10-100 parsecs and stellar mas…
Project Dinos I: A joint lensing-dynamics constraint on the deviation from the power law in the mass profile of massive ellipticals
Chin Yi Tan, Anowar J. Shajib, Simon Birrer +7
The mass distribution in massive elliptical galaxies encodes their evolutionary history, thus providing an avenue to constrain the baryonic astrophysics in their evolution. The pow…
Quantifying the stellar ages of dynamically separated bulges and disks of CALIFA spiral galaxies
Yunpeng Jin, Ling Zhu, Stefano Zibetti +3
We employ a recently developed population-orbit superposition technique to simultaneously fit the stellar kinematic and age maps of 82 CALIFA spiral galaxies and obtain the ages of…
Kinematics and Collimation of the Two-Sided Jets in NGC 4261: VLBI Study on Sub-parsec Scales
Xi Yan, Ru-Sen Lu, Wu Jiang +2
We report multi-frequency VLBI studies of the sub-parsec scale structure of the two-sided jet in the nearby radio galaxy NGC 4261. Our analyses include new observations using the S…
High-resolution APEX/LAsMA CO and CO (3-2) observation of the G333 giant molecular cloud complex : II. Survival and gravitational collapse of dense gas structures under feedback
J. W. Zhou, F. Wyrowski, S. Neupane +4
We investigate the physical properties of gas structures under feedback in the G333 complex using data of the 13CO (3-2) line in the LAsMA observation. We used the Dendrogram algor…
Chemical evolution of local post-starburst galaxies: Implications for the mass-metallicity relation
Ho-Hin Leung, Vivienne Wild, Michail Papathomas +5
We use the stellar fossil record to constrain the stellar metallicity evolution and star-formation histories of the post-starburst (PSB) regions within 45 local post-starburst gala…
The Beyond-Halo Mass Effects of the Cosmic Web Environment on Galaxies
Kuan Wang, Camille Avestruz, Hong Guo +2
Galaxy properties primarily depend on their host halo mass. Halo mass, in turn, depends on the cosmic web environment. We explore if the effect of the cosmic web on galaxy properti…
Characterizing the assembly of dark matter halos with protohalo size histories: I. Redshift evolution, relation to descendant halos, and halo assembly bias
Kai Wang, H. J. Mo, Yangyao Chen +5
We propose a novel method to quantify the assembly histories of dark matter halos with the redshift evolution of the mass-weighted spatial variance of their progenitor halos, i.e.…
The LOFAR Two-Metre Sky Survey (LoTSS): VI. Optical identifications for the second data release
M. J. Hardcastle, M. A. Horton, W. L. Williams +49
The second data release of the LOFAR Two-Metre Sky Survey (LoTSS) covers 27% of the northern sky, with a total area of deg. The high angular resolution of LOFAR wi…
JWST reveals widespread CO ice and gas absorption in the Galactic Center cloud G0.253+0.016
Adam Ginsburg, Ashley T. Barnes, Cara D. Battersby +7
We report JWST NIRCam observations of G0.253+0.016, the molecular cloud in the Central Molecular Zone known as The Brick, with the F182M, F187N, F212N, F410M, F405N, and F466N filt…
Astrometric mass measurement of compact companions in binary systems with Gaia
Yilun Wang, Shilong Liao, Nicola Giacobbo +3
For binary systems with an unseen primary and a luminous secondary, the astrometric wobble of the secondary could be used to study the primary. With Gaia, it is possible to measure…
ALMA and VLBA views on the outflow associated with an O-type protostar in G26.50+0.28
Gang Wu, Christian Henkel, Ye Xu +6
Protostellar jets and outflows are essential ingredients of the star formation process. A better understanding of this phenomenon is important in its own right as well as for many…
