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…

Mapping the Milky Way with Gaia Bp/Rp spectra-IV: the broken and asymmetric density profile of the stellar disk traced by a large sample of red clumps

Wenbo Wu, Yuqin Chen, Jianhui Lian +10

This study explores the density profile of the stellar disk, radially and azimuthally, based on approximately 8.4 million red clump stars selected from Gaia Bp/Rp spectra. After co…

Mapping the Milky Way with Gaia Bp/Rp spectra II: The inner stellar halo traced by a large sample of blue horizontal branch stars

Wenbo Wu, Xianhao Ye, C. Allende Prieto +7

We selected BHB stars based on synthetic photometry and stellar atmosphere parameters inferred from Gaia Bp/Rp spectra. We generated the synthetic SDSS broad-band and Pristin…

Investigating the vertical distribution of the disk as a function of radial action: Results from simulations

Yunpeng Jia, Chengqun Yang, Yuqin Chen +2

Previous research has established a relationship between radial action and scale height in Galactic disks, unveiling a correlation between radial and vertical heating. This finding…

Mapping the Milky Way with Gaia Bp/Rp spectra I: Systematic flux corrections and atmospheric parameters for 68 million stars

Xianhao Ye, Wenbo Wu, Carlos Allende Prieto +8

Gaia Bp/Rp spectra for over two hundred million stars have great potential for mapping metallicity across the Milky Way. We aim to construct an alternative catalog of atmospheric p…

The Stellar Abundances and Galactic Evolution Survey (SAGES) III -- The g/r/i-band Data Release

Chun Li, Zhou Fan, Gang Zhao +15

The Stellar Abundances and Galactic Evolution Survey (SAGES) is a multi-band survey that covers the northern sky area of ~12000 deg2. Nanshan One-meter Wide-field Telescope (NOWT)…
