Chasing the most distant objects
Searching for the most distant objects is important. Due to the limited time before the observed epoch, these objects can put the most stringent constraint on the structure formation in the Universe. ...

Studying the Expansion of the Universe with quasar spectra
From 2009 to 2014, the Baryon Oscillation Spectroscopic Survey (BOSS) used the SDSS telescope to obtain spectra of 1.5 million galaxies to get very accurate measurements of the Baryon Acoustic Oscilla...

Planetary Nebulae as Probes of Stellar and Galactic Evolution
Planetary nebulae (PNe) are descendants of the low- and intermediate-mass stars (about 1-8 solar masses), which account for the absolute majority (>90%) of stellar populations in the universe. As an ...

Environmental dependence of galactic properties traced by Lyα forest absorption
The link between the intergalactic medium (IGM) and galaxies is a key to understand the evolution of baryonic matter and galaxies. Although several observations have identified the presence of IGM-gal...

Revealing the galaxy intrinsic alignment with self-calibration
The galaxy intrinsic alignment (IA) is both a major source of systematic errors in weak lensing cosmology, and an emerging tracer of the large scale structure of the Universe. Separating IA from weak ...
