Observations of gamma rays from radioactive decay of $^{26}$Al have been accumulated from over 20 years with the SPI spectrometer aboard ESA’s INTEGRAL mission. $^{26}$Al decay occurs with a lifetime of one million years. This decay time is longer than the typical luminosity of supernova remnants, and allows to trace the late propagation and dynamics of ejecta from nucleosynthesis in massive...

Microquasars are the compact objects generally including accreting black holes which produce relativitic jets. The physical mechanisms of jet launching, collimation, and acceleration are poorly understood. Microquasars show strong variability in multi-wavelength observations. In X-rays, the sources show the fast variation features up to millisecond time scales, with the prominant quasiperiodic...

The formation and evolution of the Milky Way have always been cutting-edge fields in contemporary astronomy, while large-scale surveys provide us unexpected opportunities to deeply explore our home galaxy. This talk will briefly introduce the new picture of the Milky Way presented based on the huge LAMOST database. From chemical enrichment to the formation history, the LAMOST spectroscopic...

concept of dynamic Universe, the forefront of which currently is situated in radio bands and manifests itself as fast radio bursts (FRB). The discovery of FRBs was awarded the 2023 Shaw prize in astronomy. We built the largest radio telescope,... -

Lithium is a fragile but crucial chemical element in the Universe, and exhibits interesting and complex behaviors. Based on the LAMOST medium resolution spectra, we determined the lithium abundances for more than 450,000 stars. We use a sample of giants with known evolutionary phases and lithium abundances from the LAMOST-Kepler and LAMOST-K2 fields, we construct mass–radius diagrams to...
