A Hydro-Based MCMC Analysis of SNR 0509-67.5 Revealing the Explosion Properties from Fluid Discontinuities Alone
Autor: Prasiddha Arunachalam, John P. Hughes, Luke Hovey, Kristoffer Eriksen
Using HST narrow-band H{\alpha} images of supernova remnant 0509-67.5 taken {\sim}10 years apart, we measure the forward shock (FS) proper motions (PMs) at 231 rim locations. The average shock radius and velocity are 3.66 {\pm} 0.036 pc and 6315 {\pm

Head-to-Toe Measurement of El Gordo: Improved Analysis of the Galaxy Cluster ACT-CL J0102-4915 with New Wide-field Hubble Space Telescope Imaging Data
Autor: Jinhyub Kim, M. James Jee, John P. Hughes, Mijin Yoon, Kim HyeongHan, Felipe Menanteau, Cristóbal Sifón, Luke Hovey, Prasiddha Arunachalam
We present an improved weak-lensing (WL) study of the high$-z$ $(z=0.87)$ merging galaxy cluster ACT-CL J0102-4915 (El Gordo) based on new wide-field Hubble Space Telescope (HST) imaging data. The new imaging data cover the 3.5$\times$3.5 Mpc region

Constraints on Cosmic-ray Acceleration Efficiency in Balmer Shocks of Two Young Type Ia Supernova Remnants in the Large Magellanic Cloud
Autor: Curtis McCully, Viraj Pandya, John P. Hughes, Luke Hovey, Kristoffer A. Eriksen
Publikováno v: NASA Astrophysics Data System
We present results from an optical study of two young Balmer-dominated remnants of SNIa in the Large Magellanic Cloud, 0509$-$67.5 and 0519$-$69.0, in an attempt to search for signatures of efficient cosmic-ray (CR) acceleration. We combine proper mo

A kinematic study of 0509-67.5, the second youngest supernova remnant in the Large Magellanic Cloud, and its astrophysical implications
Autor: Luke Hovey
Publikováno v: NASA Astrophysics Data System
Supernova remnants are the lasting interactions of shock waves that develop in the wake of supernovae. These remnants, especially those in our galaxy and our companion galaxies, allow us to study supernovae for thousands of years after the initial st

A DIRECT MEASUREMENT OF THE FORWARD SHOCK SPEED IN SUPERNOVA REMNANT 0509–67.5: CONSTRAINTS ON THE AGE, AMBIENT DENSITY, SHOCK COMPRESSION FACTOR, AND ELECTRON–ION TEMPERATURE EQUILIBRATION
Autor: Luke Hovey, John P. Hughes, Kristoffer A. Eriksen
Publikováno v: The Astrophysical Journal. 809:119
Two Hubble Space Telescope narrow-band H? images separated in time by 1.03 years are used for a proper motion measurement of the forward shock of the LMC supernova remnant 0509?67.5, the only spectroscopically confirmed LMC remnant of Ia origin. We m
