SHAO Astrophysics Colloquia 

Title: A short introduction to gravitational wave and gravitational wave astrophysics

Speaker: Prof. Youjun Lu (NAOC)

Time: 3 PM, Dec. 01 (Thursday) 

Location: Lecture Hall, 3rd floor

Abstract: Gravitational wave, ripples in the fabric of spacetime, is a major prediction of Einstein's General Relativity (GR) and is one of the most profound nature of gravity. LIGO team recently announced the first direct detection of gravitational wave, emitted from a binary black hole merger, which not only confirms the prediction of GR but also opens an unprecedented new window ontothe cosmos--a window of gravitational wave astronomy. In this Lecture, I will give a short introduction to gravitational wave and those methods to detect gravitational waves. I will also briefly overview the field of gravitational wave astrophysics and talk about the prospects of this field.

Time:9:30-11:00,Dec. 01(Thursday) 

Speaker: Iulia Simion

Title: The Age and Structure of the Galactic Bulge from Mira Variables


Catchpole et al. 2016 study the Milky Way Bulge structure as a function of age using a sample of ~8700 Mira Variables from the OGLE and Macho surveys combined with independent observations. Distances to these stars are derived from a period-luminosity relation together with corrections for interstellar and circumstellar extinction. It is shown that both in the inner and outer regions of the Bulge the longer period Miras, tracers of an intermediate age population (~5 Gyrs and younger), give evidence of a tilted bar-like structure. They also show a clumpy structure possibly part of an X-structure.  The distribution of the shorter period (metal-rich globular cluster age) Miras, appears spheroidal in the outer bulge.

The Astrophysics division is the main group engaged in astrophysical research at Shanghai Astronomical Observatory. Research areas include active galactic nuclei and high energy astrophysics, galaxy formation and evolution, cosmology and large scale structure, star clusters and the structure of the Milk Way, star formation, and planetary astrophysics. There are now 45 faculty members, 16 postdocs, and 65 graduate students in the division.

The Astrophysics division maintains close partnerships with many astronomical research institutes, including the joint Key laboratory of research in galaxies and cosmology of CAS with University of Science and Technology of China, the joint astrophysics center with Xiamen University. Members of the astrophysics division also participate in many international and domestic astronomical projects, including LAMOST, HXMT, FAST, the Sloan Digital Sky Survey IV, TMT, LSST, etc.
