Physics-Informed Surrogate for Sb2S3 Dispersion Trimming in Thin-Film Lithium Niobate

Shoumik Debnath, Anup Kumar Modak, Sudipta Saha

A film-thickness error of 8 nm, within the tolerance of commercial thin-film lithium niobate wafers, shifts the group-velocity dispersion at 1550 nm by about 28 ps km$^{-…

Long Tidal Tails of NGC 5024 Hidden in LMS-1 and NGC 5053 Tidal Streams

Xianhao Ye, Yong Yang, Jingkun Zhao +3

We report the discovery of long tidal tails associated with the globular cluster (GC) NGC 5024. A modified matched filter applied to Gaia DR3 data reveals a broad stellar stream sp…

Chemical abundances of seven stars in the GD-1 stream

Jing-Kun Zhao, Guang-Wei Li, Wako Aoki +13

We present the first detailed chemical abundances for seven GD-1 stream stars from Subaru/HDS spectroscopy. Atmospheric parameters were derived via color calibrations (…

A Dwarf Galaxy Debris Stream Associated with Palomar 1 and the Anticenter Stream

Yong Yang, Jing-Kun Zhao, Xian-Hao Ye +2

We report the discovery of a new stream (dubbed as Yangtze) detected in Data Release 3. The stream is at a heliocentric distance of 9.12 kpc and spans nearly 27 by…

Existence of Tidal Tails for the Globular Cluster NGC 5824

Yong Yang, Jing-Kun Zhao, Miho N. Ishigaki +5

Context. Several dynamically cold streams have been associated with certain globular clusters (GCs) based on orbital energies and angular momenta. Some of these streams are surpris…

A New Cold Stream near the Southern Galactic Pole

Yong Yang, Jing-Kun Zhao, Xiang-Xiang Xue +2

We report the discovery of a cold stream near the southern Galactic pole (dubbed as SGP-S) detected in Early Data Release 3. The stream is at a heliocentric distance of $\si…

Revisit of open clusters UPK 39, UPK 41 and PHOC 39 : a new binary open cluster found

Xianhao Ye, Jingkun Zhao, Terry D. Oswalt +2

We investigate the three open clusters near Aquila Rift cloud, named as UPK 39 (\texttt{c1} hereafter), UPK 41 (\texttt{c2} hereafter) in Sim et al. (2019) and PHOC 39 (\texttt{c3}…

Revisit NGC 5466 Tidal Stream with , SDSS/SEGUE and LAMOST

Yong Yang, Jing-Kun Zhao, Miho N. Ishigaki +5

By mining the data from EDR3, SDSS/SEGUE DR16 and LAMOST DR8, 11 member stars of the NGC 5466 tidal stream are detected and 7 of them are newly identified. To reject contami…
