Extended Tidal Tails of IC 4756 detected by {\it Gaia} EDR3
Xianhao Ye, Jinkun Zhao, Jiajun Zhang +2
We report the discovery of emerged tidal tails around open cluster IC 4756 ( 1 Gyr) based on 644 members identified from {\it Gaia} EDR3. Three-dimensional spatial positions,…
Baryon Acoustic Oscillations from Integrated Neutral Gas Observations: an instrument to observe the 21cm hydrogen line in the redshift range 0.13 z 0.45 -- status update
Carlos A. Wuensche, Elcio Abdalla, Filipe Batoni Abdalla +48
BINGO (BAO from Integrated Neutral Gas Observations) is a unique radio telescope designed to map the intensity of neutral hydrogen distribution at cosmological distances, making th…
Nearly 30,000 late-type main-sequence stars with stellar age from LAMOST DR5
Jiajun Zhang, Jingkun Zhao, Terry D. Oswalt +3
We construct a sample of nearly 30,000 main-sequence stars with 4500K 5000K and stellar ages estimated by the chromospheric activityage relation. This sample is u…
Towards a Bias-Free Selection Function in Shear Measurement
Hekun Li, Jun Zhang, Dezi Liu +5
Sample selection is a necessary preparation for weak lensing measurement. It is well-known that selection itself may introduce bias in the measured shear signal. Using image simula…
A study on Cubic Galileon Gravity Using N-body Simulations
Jiajun Zhang, Bikash R. Dinda, Md. Wali Hossain +2
We use N-body simulation to study the structure formation in the Cubic Galileon Gravity model where along with the usual kinetic and potential term we also have a higher derivative…
A new moving group in the Local Arm
Xilong Liang, Jingkun Zhao, Yuqin Chen +5
We present a new moving group clustered in kinematics, spatial position and elemental abundances. Its spatial position is around the center of the Local Arm of the Milky Way. A con…
