Natsuki H. Hayatsu
Ph.D. in Physics (Astrophysicist)
I'm a postdoctoral researcher from Japan.
My science goal is to understand cosmic star-formation history.
駆け出しの天文学者です。
主に「宇宙の星形成史」や「遠方宇宙の星形成」に興味があります。
Latest news:
18-19/03/2023 contributed talk at a semi-ana galaxy formation workshop (+LOC, Ja, on site at Ishigakijima Astronomical Observatory)
01/03/2023 Hayatsu et al. (b) submitted. This project is a kind of halted for a few years for many reasons. I sincerely thank the co-authors for their encouragements!
28/02/2023 contributed talk at OISTER workshop (+SOC, Ja, remote)
12/01/2023 invited talk at VLTI and ALMA Synthesis Imaging Workshop, ESO (En, on site).
17/11/2022 Hayatsu et al. (a) submitted. It had been submitted once as a letter, but now it is switched to a normal journal.
Projects
What I'm working on
HELioS
I tentatively named this project HELioS; discovery of a Hidden galaxy in an Enriched Line of Sight.
I have organized an international workshop in March 2020. The left is the group photo! As you see, it was unfortunately a remote meeting due to the COVID-19 pandemic, but the workshop was very active and we had fruitful discussions. Now we're preparing/submitting some papers and proposals!
BLiSS
This is my PhD project. We have developed a method to detect line-emitter blindly with the statistical reliability.
I made a script to find a clump in the 3-dim data and my former colleague kindly named it BLiSS; Blind Line Search Script.
My first paper is here. A figure in it became a front image of PASJ (left). We published the second result as a research note (here).I haven't given up to release the developed code in the future! There will be more to come.
