The Origin of the Mg-rich Supernova Remnant J0550-6823 and the Frequency of Similar Events in the Large Magellanic Cloud
Yui Kuboike, Toshiki Sato, Hiromasa Suzuki +4
Shell burning and internal mixing in massive stars play an important role in setting the initial conditions for core-collapse supernova explosions. In the late stages of stellar ev…
Inhomogeneous stellar mixing in the final hours before the Cassiopeia A supernova
Toshiki Sato, Kai Matsunaga, Hiroyuki Uchida +10
Understanding stars and their evolution is a key goal of astronomical research and has long been a focus of human interest. In recent years, theorists have paid much attention to t…
Destratification in the Progenitor Interior of the Mg-rich Supernova Remnant N49B
Toshiki Sato, Kai Matsunaga, Ryo Sawada +6
Simulations of pre-supernova evolution suggest that some intense shell burning can be so active that, in extreme cases, it can merge with the outer shell, changing the initial cond…
Missing Titanium in the Asymmetric Supernova Remnant W49B
Toshiki Sato, Makoto Sawada, Keiichi Maeda +2
The progenitor of the W49B supernova remnant is still under debate. One of the candidates is a jet-driven core-collapse supernova. In such a highly asymmetric explosion, a strong $…
Temperature Structure in the Perseus Cluster Core Observed with Hitomi
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +192
The present paper investigates the temperature structure of the X-ray emitting plasma in the core of the Perseus cluster using the 1.8--20.0 keV data obtained with the Soft X-ray S…
Detection of the pairwise kinematic Sunyaev-Zel'dovich effect with BOSS DR11 and the Atacama Cosmology Telescope
F. De Bernardis, S. Aiola, E. M. Vavagiakis +55
We present a new measurement of the kinematic Sunyaev-Zeldovich effect using data from the Atacama Cosmology Telescope (ACT) and the Baryon Oscillation Spectroscopic Survey (BOSS).…
Evidence for Type Ia Supernova Diversity from Ultraviolet Observations with the Hubble Space Telescope
Xiaofeng Wang, Lifan Wang, Alexei V. Filippenko +93
We present ultraviolet (UV) spectroscopy and photometry of four Type Ia supernovae (SNe 2004dt, 2004ef, 2005M, and 2005cf) obtained with the UV prism of the Advanced Camera for Sur…
ACTPol: A polarization-sensitive receiver for the Atacama Cosmology Telescope
M. D. Niemack, P. A. R. Ade, J. Aguirre +39
The six-meter Atacama Cosmology Telescope (ACT) in Chile was built to measure the cosmic microwave background (CMB) at arcminute angular scales. We are building a new polarization…
Abundance Inhomogeneity in the Northeastern Rim of the Cygnus Loop Revealed by Suzaku Observatory
S. Katsuda, H. Tsunemi, H. Uchida +5
We present the results of a spatially resolved spectral analysis from four Suzaku observations covering the northeastern rim of the Cygnus Loop. A two-kT_e non-ionization equilibri…
Chandra Observations of Unresolved X-ray Sources around two Clusters of Galaxies
S. M. Molnar, J. P. Hughes, M. Donahue +1
We have searched for unresolved X-ray sources in the vicinity of two rich clusters of galaxies: Abell 1995 (A1995) and MS 0451.6-0305 (MS0451), using the Chandra X-ray observatory.…
The Expansion of the X-ray Remnant of Tycho's Supernova (SN1572)
John P. Hughes
Two ROSAT high resolution images separated by nearly five years have been used to determine the expansion of the X-ray remnant of Tycho's supernova (SN1572). The current expansion…
