Discovery of a star sensitive to the spin of Sgr A*
K. Abd El Dayem, R. Abuter, N. Aimar +85
The paper reports the discovery of a faint main‑sequence star (S301) on an 8.7‑year, highly eccentric orbit around the Milky Way’s central black hole, whose high velocity makes its…
Using VLTI/GRAVITY+ to determine the identity of a third planet candidate in the PDS 70 system
David Trevascus, Wolfgang Brandner, Olga Balsalobre-Ruza +75
Detections of protoplanets are rare and protoplanetary disk features mischaracterized as planets are common. PDS 70 is one of only two stars known to host multiple confirmed protop…
The Extreme Rarity and Physical Properties of Low-redshift AGNs with Balmer Absorption
Jinyi Shangguan, Chang-Hao Chen, Luis C. Ho +6
Balmer absorption lines are increasingly observed in the little red dots (LRDs) discovered by the James Webb Space Telescope, potentially tracing dense circumnuclear gas around rap…
ABCD: The Nuclear Structure of the Little Red Dots Revealted through Absorption, Break, Continuum, and Decrement
Chang-Hao Chen, Jinyi Shangguan, Luis C. Ho +3
We present a spectroscopic analysis of 14 little red dots (LRDs) at redshifts using NIRSpec/MSA prism and medium-resolution grating observations, aiming to constrai…
The Emergence of Little Red Dots from Binary Massive Black Holes
Kohei Inayoshi, Jinyi Shangguan, Xian Chen +2
Little red dots (LRDs) are a newly identified class of broad-line active galactic nuclei (AGN) with a distinctive v-shape spectrum characterized by red optical and blue UV continuu…
CSST Preparations: Galaxy Completeness and Sérsic Profile Fitting across the Wide, Deep, and Extreme Fields
Ziqi Ma, Si-Yue Yu, Taotao Fang +3
The upcoming imaging survey of the Chinese Space-station Survey Telescope (CSST) will deliver high-resolution imaging of an unprecedented number of galaxies for galaxy studies. To…
