Rotation-induced Relaxation of Supernova Constraints on Axionlike Particles
Tsurugi Takata, Kanji Mori, Ko Nakamura +1
We study how rotation modifies the constraints on MeV-scale axion-like particles (ALPs) coupled to photons derived from SN 1987A. We constrain the ALP parameter space based on both…
An expanding ring of the hypercompact HII region W49N:A2
Ryosuke Miyawaki, Masahiko Hayashi, Tetsuo Hasegawa
We present 250~GHz continuum and H29alpha line data toward W49N:A2, a hypercompact HII region ionized by an O9 star. The data obtained with ALMA at a resolution of ~0"05 (600 au) c…
W49N MCN-a: a disk accreting massive protostar embedded in an early-phase hot molecular core
Ryosuke Miyawaki, Masahiko Hayashi, Tetsuo Hasegawa
We present ALMA archival data for 219-235 GHz continuum and line observations toward the hot molecular core (HMC) W49N MCN-a (UCHII region J1) at a resolution of ~0."3. The dust co…
ALMA Astrometry of the Objects within 0.5 pc of Sagittarius A
Masato Tsuboi, Takahiro Tsutsumi, Atsushi Miyazaki +2
Atacama Large Millimeter/Submillimeter Array (ALMA) is promising to be a powerful tool for precision astrometry of the area around Sagittarius A (Sgr A) because it ha…
Time dependent field correlators from holographic EPR pairs
Shoichi Kawamoto, Da-Shin Lee, Chen-Pin Yeh
We study the correlators of the fields that couple to the quark and anti-quark EPR pair in the super Yang-Mills theory using the holographic description, which is a string in AdS s…
Star burst in W49N presumably induced by cloud-cloud collision
Ryosuke Miyawaki, Masahiko Hayashi, Tetsuo Hasegawa
We present high resolution observations of CS(J=1-0), H13CO+ (J=1-0), and SiO(v=0:J=1-0) lines, together with the 49GHz and 86GHz continuum emissions, toward W49N carried out with…
