A WENO Algorithm of the Temperature and Ionization Profiles around a Point Source
Jing-Mei Qiu, Long-Long Feng, Chi-Wang Shu +1
We develop a numerical solver for radiative transfer problems based on the weighted essentially nonoscillatory (WENO) scheme modified with anti-diffusive flux corrections, in order…
Multi-wavelength Study of Young Massive Star Clusters in the Interacting Galaxy ARP 24
Chen Cao, Hong Wu
We made a multi-wavelength study of young massive star clusters (YSCs) in the interacting galaxy ARP 24, using the optical and ultraviolet images from Hubble Space Telescope (HST),…
The young stellar population in M17 revealed by Chandra
Patrick S. Broos, Eric D. Feigelson, Leisa K. Townsley +5
We report here results from a Chandra ACIS observation of the stellar populations in and around the Messier 17 H II region. The field reveals 886 sources, 771 of which have stellar…
On the nature of the flares from three candidate tidal disruption events
Y. Lu, Z. Zheng, S. N. Zhang +1
The X-ray flares of NGC 5905, RX J1242.6-1119A, and RX J1624.9+7554 observed by Chandra in 2001 and 2002 have been suggested as the candidate tidal disruption events. The distinct…
Making a Short Gamma-Ray Burst from a Long one: Implications for the Nature of GRB 060614
Bing Zhang, Bin-Bin Zhang, En-Wei Liang +3
The absence of a supernova accompanying the nearby long GRB 060614 poses a great puzzle about the progenitor of this event and challenges the current GRB classification scheme. Thi…
Characteristics of supernova remnant G351.7+0.8 and a distance argument against its association with PSR J1721-3532
W. W. Tian, M. Haverkorn, H. Y. Zhang
New images of the supernova remnant (SNR) G351.7+0.8 are presented based on 21cm HI-line emission and continuum emission data from the Southern Galactic Plane Survey (SGPS). SNR G3…
