I gave an outreach talk to high school students. It was about how astrophysicists probe the origin and the expansion of the Universe!

A series of DESI papers about how the DESI survey was designed, operated, and validated is out today! I am fortunate to lead one of the papers and contribute to the DESI project.

2022 Nov 23 update - The galaxy VI paper is now accepted in ApJ.

2022 July

A HST archival project --- A ULLYSES Survey of the Magellanic Clouds: a Laboratory for the Physics of Interfaces between Hot and Cold Gas --- that I participate as a Co-Investigator is approved!

NTU Institute of Astrophysics and Department of Physics are now a member of the DESI collaboration. I can't wait to use DESI data to do great astrophysical science!

2022 April 1

I join ASIAA as a joint assistant research fellow!

2022 Jan 26

My MOST proposal "Unveiling the Physical Processes Driving Galaxy Evolution with the Dark Energy Spectroscopic Instrument Survey" (運用DESI計畫大數據探究星系演化的物理機制) is approved! Thank you for your support, MOST.

2022 Jan 15

My joint proposal with NTU high-energy group "Synergies of Astrophysics and Particle Physics" (天文與粒子物理的協同研究) for the NTU core consortium program is approved! Thank you for having me, NTU high-energy group, and for your support, NTU!

DESI has already collected 7.5 million spectra of galaxies --- an amount more than all the previous spectroscopic surveys combined together!

A slice through the 3D map of galaxies from the first few months of the DESI survey. The Earth is at the center, with the furthest galaxies plotted at distances of 10 billion light-years. Each point represents one galaxy. This version of the DESI map shows a subset of 400,000 of the 35 million galaxies that will be in the final map. Image credit: D.

I start my position as an assistant professor at National Taiwan University!

2021 July 24

I am awarded as a Yushan young scholar (2021-2026) by the Ministry of Education in Taiwan.

2021 July 2

I wrote an article about my academic experience and some suggestions for those who would like to pursue a career in academia, especially in astronomy.

DESI starts its main survey operation TODAY!

Press release:

3D visualization:

DESI will collect more than 30,000,000 spectra of stars, galaxies, and quasars and map the 3D distribution of matters in the Universe. I can not wait to work on such an amazing dataset!

Over the past year, I have been leading the effort of building truth redshift tables of galaxies from the survey validation dataset and using the tables to better understand the target selection, redshift completeness and the performance of the pipeline. I am really happy to be part of this survey.

2021 May 13

Hiroyuki Hirashita and I wrote a paper about the origin(s) of small dust grains in the CGM and the paper is now accepted! Thank you Hirashita-san for having me on this project.

2021 March 11

I am doing a remote observation with the Harlan J. Smith 2.7m Telescope at the McDonald Observatory.

2021 Jan 29

I got my giant radio galaxy paper accepted by MNRAS.

This is my 10th first-author paper! This work is done in collaboration with Prof. Xavier Prochaska at UCSC.
