Why Dark Matter May Have Self-Interactions
Dark matter makes up most of the matter in the Universe, yet its fundamental nature remains unknown. In this talk, I will present recent high-resolution N-body simulations of self-interacting dark matter and discuss their implications for a wide range of astrophysical observations. I will highlight new signatures associated with gravothermal collapse in dark matter halos and show how they may b...

中子超流涡旋的脉冲星效应
1)研究了中子星内部超流涡旋运动中子的中微子辐射，给出了长周期脉冲星的自转周期规律(2017年被天文观测证实);2)通过中子星的中微子辐射解释了高速中子星这种特殊的宇观现象。个人简介：彭秋和，南京大学天文与空间科学学院教授、博士生导师。1960年毕业于南京大学；1960年至1978年任教于北京大学，1978年调回南京大学。曾任多届中国天文学会及全国引力和相对论天体物理学会理事。主要从事核天体物理、高能天体物理及星系天文学...

Multi-wavelength, multi-messenger, transient astrophysics
I will review the recent progress in understanding astrophysical transients within the context of the multi-wavelength (MW) and multi-messenger (MM) observations, highlighting gamma-ray bursts (GRBs), fast X-ray transients (FXTs), and fast radio bursts (FRBs). Special attention is paid to the breakthrough observations made with the Einstein Probe and SVOM space telescopes as well as the FAST ra...

No Cluster Left Behind: Multiwavelength Cluster Analysis with All the Data
Cluster abundance is among the most powerful cosmological probes, but its constraining power is currently limited by systematic uncertainties in mass calibration. Optically selected samples in particular suffer from line-of-sight projection effects that bias both richness and lensing measurements. Jointly modeling clusters observed across multiple wavelengths offers a path to self-calibrating t...

Nebular_AGN: A CIGALE module for fitting active galactic nucleus emission lines
Active galactic nuclei (AGN) play a crucial role in regulating star formation and galaxy evolution. With the upcoming next-generation high-redshift, wide-field, multi-object spectroscopic surveys, it is increasingly important to efficiently identify AGN candidates from massive survey data and infer their physical properties via spectral and emission-line characteristics. To address this, we hav...
