In this letter, we report the discovery of an intriguing HVS (J1443+1453) candidate that is probably from the Sagittarius Dwarf Spheroidal galaxy (Sgr dSph). The star is an old and…
Extended HNCO, SiO, and HCN emission in 43 southern star-forming regions
Yu-Xin He, Christian Henkel, Jian-Jun Zhou +9
We have selected 43 southern massive star-forming regions to study the spatial distribution of HNCO 4-3, SiO 2-1 and HCN 10-9 line emission and to investigate t…
Observations of magnetic fields surrounding LkH 101 taken by the BISTRO survey with JCMT-POL-2
Nguyen Bich Ngoc, Pham Ngoc Diep, Harriet Parsons +146
We report the first high spatial resolution measurement of magnetic fields surrounding LkH 101, a part of the Auriga-California molecular cloud. The observations were taken with…
New Determination of Fundamental Properties of Palomar 5 Using Deep DESI Imaging Data
Xin Xu, Hu Zou, Xu Zhou +6
The legacy imaging surveys for the Dark Energy Spectroscopic Instrument project provides multiplecolor photometric data, which are about 2 mag deeper than the SDSS. In this study,…
Predictions for the FAST telescope's CRAFTS Extra-Galactic HI Survey
Kai Zhang, Jingwen Wu, Di Li +7
The Five-hundred-meter Aperture Spherical radio Telescope (FAST) has started the Commensal Radio Astronomy FasT Survey (CRAFTS). In this paper, we use the technical parameters of F…
An Extended Halo-based Group/Cluster finder: application to the DESI legacy imaging surveys DR8
Xiaohu Yang, Haojie Xu, Min He +20
We extend the halo-based group finder developed by \citet[][]{Yang2005a} to use data {\it simultaneously} with either photometric or spectroscopic redshifts. A mock galaxy redshift…
Hosts and triggers of AGNs in the Local Universe
Ziwen Zhang, Huiyuan Wang, Wentao Luo +11
Based on the spectroscopic and shear catalogs for SDSS galaxies in the local Universe, we compare optically-selected active galactic nuclei (AGNs) with control star-forming and qui…
ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP): Detection of extremely high density compact structure of prestellar cores and multiple substructures within
Dipen Sahu, Sheng-Yuan Liu, Tie Liu +38
Prestellar cores are self-gravitating dense and cold structures within molecular clouds where future stars are born. They are expected, at the stage of transitioning to the protost…
Auto-identification of unphysical source reconstructions in strong gravitational lens modelling
Jacob Maresca, Simon Dye, Nan Li
With the advent of next-generation surveys and the expectation of discovering huge numbers of strong gravitational lens systems, much effort is being invested into developing autom…
A Spitzer survey of Deep Drilling Fields to be targeted by the Vera C. Rubin Observatory Legacy Survey of Space and Time
M. Lacy, J. A. Surace, D. Farrah +60
The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) will observe several Deep Drilling Fields (DDFs) to a greater depth and with a more rapid cadence than the main…
Estimating ages and metallicities of M31 star clusters from LAMOST DR6
Shoucheng Wang, Bingqiu Chen, Jun Ma
Context. Determining the metallicities and ages of M31 clusters is fundamental to the study of the formation and evolution of M31 itself. The Large Sky Area Multi-Object Fiber Spec…
