ABSTRACT Type Ia supernovae (SNe Ia) are important cosmological probes and
contributors to galactic nucleosynthesis, particularly of the iron group elements. To improve …

We present six epochs of optical spectropolarimetry of the Type IIP supernova (SN) 2021yja

Mrk 501 is a prototypical high-synchrotron-peaked blazar and serves as one of the primary
targets for the Imaging X-ray Polarimetry Explorer (IXPE). In this study, we report X-ray …

The Tsinghua University–Ma Huateng Telescopes for Survey (TMTS) started to monitor the
LAMOST plates in 2020, leading to the discovery of numerous short-period eclipsing …
