The Reliability of Accretion Disk Inclination Derived from X-ray Spectroscopy of Active Galaxies

Kavli Affiliate: Luis C. Ho | First 5 Authors: Rong Du, Yuanze Ding, Luis C. Ho, Ruancun Li, | Summary: The inclination angle of substructures in active galaxies gives insights into physical components from scales of the vicinity of the central black hole to the entire host galaxy. We use the self-consistent reflection spectral model […]

Photoevaporation from Inner Protoplanetary Disks Confronted with Observations

Kavli Affiliate: Lile Wang | First 5 Authors: Yiren Lin, Lile Wang, Min Fang, Ahmad Nemer, Jeremy Goodman | Summary: The decades-long explorations on the dispersal of protoplanetary disks involve many debates about photoevaporation versus magnetized wind launching mechanisms. This letter argues that the observed winds originating from the inner disk ($Rlesssim 0.3$ AU) cannot […]

Modeling the wavelength dependence of photo-response non-uniformity of a CCD sensor

Kavli Affiliate: Hu Zhan | First 5 Authors: Zun Luo, Wei Du, Baocun Chen, Xianmin Meng, Hu Zhan | Summary: Precision measurements of astrometry and photometry require stringent control of systematics such as those arising from imperfect correction of sensor effects. In this work, we develop a parametric method to model the wavelength dependence of […]

On the Scarcity of Dense Cores ($n>10^{5}$ cm$^{-3}$) in High Latitude Planck Galactic Cold Clumps

Kavli Affiliate: Ke Wang | First 5 Authors: Fengwei Xu, Ke Wang, Tie Liu, David Eden, Xunchuan Liu | Summary: High-latitude ($|b|>30^{circ}$) molecular clouds have virial parameters that exceed 1, but whether these clouds can form stars has not been studied systematically. Using JCMT SCUBA-2 archival data, we surveyed 70 fields that target high-latitude Planck […]

Non-symmetrical sparking may hint “zits” on a pulsar surface

Kavli Affiliate: Renxin Xu | First 5 Authors: Zhengli Wang, Jiguang Lu, Jingchen Jiang, Shunshun Cao, Weiyang Wang | Summary: Pulsar electrodynamics could be relevant to the physics of stellar surface, which remains poorly understood for more than half a centenary and is difficult to probe due to the absence of direct and clear observational […]
