Identifying the principal mechanism of star formation feedback
Chong Li, Rouyu Li, Keping Qiu +27
Feedback from massive stars regulates the formation of next-generation stars and planets and thus shapes the evolution of galaxies, yet observational evidence capable of determinin…
Possible evidence for extended X-ray emission surrounding PSR B0656+14 with eROSITA
Shu Niu, Qiang Yuan, Shui-Nai Zhang +3
Extended very-high-energy -ray emission from middle-aged pulsars as revealed recently by several groundbased -ray experiments has strong implication on the transport of high-…
A Monte-Carlo Simulation on Resonant Scattering of X-ray Line Emission in Supernova Remnants
Yiping Li, Gao-Yuan Zhang, Yang Chen +2
Resonant scattering (RS) of X-ray line emission in supernova remnants (SNRs) may modify the observed line profiles and fluxes and has potential impact on estimating the physical pr…
Scientific Objectives of the Hot Universe Baryon Surveyor (HUBS) Mission
Joel Bregman, Renyue Cen, Yang Chen +51
The Hot Universe Baryon Surveyor (HUBS) is a proposed space-based X-ray telescope for detecting X-ray emissions from the hot gas content in our universe. With its unprecedented spa…
Hierarchical Structure of YSO Clusters in the W40 and Serpens South Region: Group Extraction and Comparison with Fractal Clusters
Jia Sun, Robert A. Gutermuth, Hongchi Wang +2
Young stellar clusters are believed to inherit the spatial distribution like hierarchical structures of their natal molecular cloud during their formation. However, the change of t…
Deep Near-Infrared Survey Toward the W40 and Serpens South Region in Aquila Rift: A Comprehensive Catalog of Young Stellar Objects
Jia Sun, Robert A. Gutermuth, Hongchi Wang +5
Active star forming regions are excellent laboratories for studying the origins and evolution of young stellar object (YSO) clustering. The W40 - Serpens South region is such a reg…
X-ray Spectroscopic Evidence of Charge Exchange Emission in the Disk of M51
Shuinai Zhang, Q. Daniel Wang, Wei Sun +3
In the disks of spiral galaxies, diffuse soft X-ray emission is known to be strongly correlated with star-forming regions. However, this emission is not simply from a thermal-equil…
Timing and spectral variability of high mass X-ray pulsar GX 301--2 over orbital phases observed by Insight-HXMT
Y. Z. Ding, W. Wang, P. R. Epili +7
We report the orbital X-ray variability of high mass X-ray binary (HMXB) GX301--2. GX301--2 undergone a spin up process in 2018--2020 with the period evolving from 685 s to…
TeV cosmic ray nuclei acceleration in shell-type supernova remnants with hard -ray spectra
Houdun Zeng, Yuliang Xin, Shuinai Zhang +1
The emission mechanism for hard -ray spectra from supernova remnants (SNRs) is still a matter of debate. Recent multi-wavelength observations of TeV source HESS J1912+101 show t…
Mapping Diffuse Emission in Lyman UV band
Li Ji, Zheng Lou, Jinlong Zhang +38
The CAFE (Census of warm-hot intergalactic medium, Accretion, and Feedback Explorer) and LyRIC (Lyman UV Radiation from Interstellar medium and Circum-galactic medium) have been pr…
Spectral Modeling of Charge Exchange in the Central Region of M51
Hang Yang, Shuinai Zhang, Li Ji
Charge exchange (CX) emission reveals the significant interaction between neutral and ionized interstellar medium (ISM) components of the dense, multiphase, circumnuclear region of…
Charge exchange emission and cold clumps in multi-phase galactic outflows
Kinwah Wu, Kaye Jiale Li, Ellis R. Owen +3
Large-scale outflows from starburst galaxies are multi-phase, multi-component fluids. Charge-exchange lines which originate from the interfacing surface between the neutral and ion…
Resonant scattering effect on the soft X-ray line emission from the hot interstellar medium: I. galactic bulges
Yang Chen, Q. Daniel Wang, Gao-Yuan Zhang +2
Diffuse soft X-ray line emission is commonly used to trace the thermal and chemical properties of the hot interstellar medium, as well as its content, in nearby galaxies. Although…
