X-ray variability of SDSS J000532.84+200717.4: from a normal state to an X-weak state
Xiaohui Yang, Yanli Ai, Liming Dou +8
We present a multi-epoch study of the extreme X-ray variability of the type~1 quasar SDSS~J000532.84+200717.4 using archival observations from \textit{XMM-Newton}, \textit{Swift}/X…
Submillimeter and Mid-Infrared Variability of Young Stellar Objects in the M17 HII Region
Zhiwei Chen, Doug Johnstone, Carlos Contreras Peña +12
We conducted a comprehensive analysis of young stellar object (YSO) variability at submillimeter and mid-infrared (mid-IR) wavelengths for the M\,17 \ion{H}{2} region, using 3.5 ye…
Submillimeter and Mid-Infrared Variability of Young Stellar Objects in the M17SWex Intermediate-Mass Star-Forming Region
Geumsook Park, Doug Johnstone, Carlos Contreras Pena +12
We present a comprehensive analysis of young stellar object (YSO) variability within the M17 Southwest Extension (M17 SWex), using 3.5 years of monitoring data from the JCMT Transi…
Surveys of clumps, cores, and condensations in Cygnus X: Temperature and nonthermal velocity dispersion revealed by VLA NH3 observations
Xu Zhang, Keping Qiu, Qizhou Zhang +6
The physical properties, evolution, and fragmentation of massive dense cores (MDCs, 0.1 pc) are fundamental pieces in our understanding of high-mass star formation. We aim t…
The JCMT Transient Survey: Six-Year Summary of 450/850\,m Protostellar Variability and Calibration Pipeline Version 2.0
Steve Mairs, Seonjae Lee, Doug Johnstone +15
The JCMT Transient Survey has been monitoring eight Gould Belt low-mass star-forming regions since December 2015 and six somewhat more distant intermediate-mass star-forming region…
Surveys of clumps, cores, and condensations in Cygnus-X:Searching for circumstellar disks
Xing Pan, Keping Qiu, Kai Yang +2
To investigate whether disk-mediated accretion is the primary mechanism in high-mass star formation, we have established a survey of a large sample of massive dense cores within a…
