No Surviving Companion to the Galactic SN 1181: Evidence for a Double-Degenerate Channel for Type Iax Supernovae

Kohki Uno, Daichi Tsuna, Daichi Hiramatsu +2

Type Iax supernovae (SNe Iax) are the recently-established, yet peculiar subclass of thermonuclear supernovae, whose progenitor systems and explosion mechanisms remain debated. A l…

Constraint on the progenitor of binary black hole merger using Population III star formation channel

Masaki Iwaya, Tomoya Kinugawa, Hideyuki Tagoshi

The observations of gravitational waves have revealed the existence of black holes above . A variety of channels have been proposed as their origin, including the Popul…

Hidden in Pixels I: Discovery of dual "little red dots" indicates excess clustering on kilo-parsec scales

Takumi S. Tanaka, John D. Silverman, Kazuhiro Shimasaku +56

``Little Red Dots'' (LRDs) are an abundant high-redshift population newly discovered by the James Webb Space Telescope (JWST) and considered to be an early growth phase of supermas…

Impact of Spin Priors on the Population Inference of Merging Binary Black Holes

Kazuya Kobayashi, Masaki Iwaya, Soichiro Morisaki +2

The spins of merging binary black holes (BBHs) inferred from gravitational-wave (GW) observations provide key insights into their formation channels. However, spin parameters are t…

The diffuse supernova neutrino background: an update with modern population synthesis and core-collapse simulations

Cecilia Lunardini, Tomoya Takiwaki, Tomoya Kinugawa +2

We present a new, state-of-the-art computation of the Diffuse Supernova Neutrino Background (DSNB), where we use neutrino spectra from multi-dimensional, multi-second core collapse…

Population Synthesis Study on the Binary Origin of Type Ibn Supernovae

Takatoshi Ko, Tomoya Kinugawa, Daichi Tsuna +2

Type Ibn supernovae (SNe) are a class of SN explosions whose progenitors are surrounded by dense helium-rich circumstellar matter (CSM). Some models have been proposed for how to f…
