Galaxy: emissions
- Fulai Guo (Shanghai Astronomical Observatory)
Galaxies are evolving ecosystems of multiple components which interplay with each other and are distributed over a wide range of spatial scale, from sub-galactic scales up to scales of dark matter halos. Our understanding of the galaxy ecosystems has largely been limited to relatively bright galaxies, however. Other components such as gas of different phases as well as dwarf galaxies with...
We adopt a new kind of one-dimensional model instead of the isothermal sphere to describe the radial distribution of hot gas in the L-Galaxies semi-analytic model. The hot gas halo can be divided into two parts according to the ratio of the local thermal instability time-scale and the free-fall time-scale: a cool core with tTI/tff = 10 and a stable outer halo with tTI/tff > 10. We update the...
The study of the spectral energy distribution (SED) of active galactic nuclei (AGN) plays a very important role in several aspects of AGN, such as the physics of black hole (BH) accretion, AGN feedback, and AGN luminosity function (LF). In this work, we explain the observed AGN LF with the SED more physically considered. Specifically, we strictly study the accretion model for a wide range of...
UVCANDELS is a HST Cycle-26 Treasury Program awarded 164 orbits of primary ultraviolet (UV) F275W imaging and coordinated parallel optical F435W imaging in four CANDELS fields: GOODS-N, GOODS-S, EGS, and COSMOS, covering a total area of $\sim430$ arcmin$^2$. This is $\sim2.5$ times larger than the area covered by previous UV data combined, reaching a depth of 27 ABmag. We present a robust...
