Detection of an Orphan X-ray Flare from a Blazar Candidate EP240709a with Einstein Probe
Mingjun Liu, Yijia Zhang, Yun Wang +49
Blazars are often observed to flare across multiple wavelengths. Orphan flares from blazars have been only detected a few times, providing an opportunity to understand the structur…
Intermediate-Mass Black Holes in Green Pea Galaxies (IMBH-GP) I: a Candidate Sample from LAMOST and SDSS
Ruqiu Lin, Zhen-Ya Zheng, Fang-Ting Yuan +8
The scaling relation of central massive black holes (MBHs) and their host galaxies is well-studied for supermassive BHs (SMBHs, ). However, th…
Probing the Shock Breakout Signal of SN 2024ggi from the Transformation of Early Flash Spectroscopy
Jujia Zhang, Luc Dessart, Xiaofeng Wang +11
We present early-time, hour-to-day cadence spectroscopy of the nearby type II supernova (SN II) 2024ggi, which was discovered at a phase when the SN shock just emerged from the red…
The Red Supergiant Progenitor of Type II Supernova 2024ggi
Danfeng Xiang, Jun Mo, Xiaofeng Wang +8
We present a detailed analysis of the progenitor and its local environment for the recently discovered type II supernova (SN) 2024ggi at a distance of about 6.7~Mpc, by utilizing t…
