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…
