2. 30/03/20 K. Lutz - Intro to my Science 2

Catinella Strasbourg (CDS, ObAS) Post-Doc: Scientific support of VO proects and all my favourite Science with CDS team, C. Bot, L. Posti, B. Vollmer
4. 30/03/20 K. Lutz - Intro to my Science 4 My current position CDS postdoc Science Functional work
5. 30/03/20 K. Lutz - Intro to my Science 5 Star formation – gas cycle Stars Old stars: Stellar winds Supernovae Accretion Star formation Cooling Condensation Dust Metals
6. 30/03/20 K. Lutz - Intro to my Science 6 Science questions Where does the cold gas come from and where does it go? Catinella et al. (2018), Saintonge, …, Lutz et al. (2017)
7. 30/03/20 K. Lutz - Intro to my Science 7 Science questions How are cold gas (HI and H 2 ), metallicity and dust correlated? Globally and locally? Bothwell et al. (2013)
8. 30/03/20 K. Lutz - Intro to my Science 8 Science questions How does the angular momentum affect galaxy evolution? Maddox et al. (2015) Romanowsky & Fall (2012)
9. 30/03/20 K. Lutz - Intro to my Science 9 All my science projects • xGASS & xCOLDGASS metallicity → metall gradients and cold gas • HIX HI-rich galaxies → metall • SHREG properties of resolved HI discs → metall • MCX SEDs between → metall μm and cm • AG/DC All gas and dust content of → metall galaxies
10. 30/03/20 K. Lutz - Intro to my Science 10 XGASS / xCOLD GASS Lutz et al. (in prep.)
11. 30/03/20 K. Lutz - Intro to my Science 11 XGASS / xCOLDGASS • Statistics are hard • Local metallicity correlates with global HI content (and not with H 2 )
12. 30/03/20 K. Lutz - Intro to my Science 12 HIX galaxies – sample selection
13. 30/03/20 K. Lutz - Intro to my Science 13 HIX galaxies
14. 30/03/20 K. Lutz - Intro to my Science 14 HIX galaxies
15. 30/03/20 K. Lutz - Intro to my Science 15 HIX galaxies – star formation Lutz et al. (2017)
16. 30/03/20 K. Lutz - Intro to my Science 17 HIX galaxies – angular momentum Lutz et al. (2018)
17. 30/03/20 K. Lutz - Intro to my Science 18 HIX galaxies – halo spin Lutz et al. (2018)
18. 30/03/20 K. Lutz - Intro to my Science 19 HIX galaxies – gas-phase metallicity Lutz et al. (2020)
19. 30/03/20 K. Lutz - Intro to my Science 20 HIX galaxies - outlook • Dust content from SED modelling • CO ALMA data
20. 30/03/20 K. Lutz - Intro to my Science 21 HIX conclusion • HIX galaxies are HI rich and average star formers • HI disc as big as can be supported by specific angular momentum • Halo spin large – High angular momentum – Slow evolution
21. 30/03/20 K. Lutz - Intro to my Science 22 SHREG – on sky distribution
22. 30/03/20 K. Lutz - Intro to my Science 23 SHREG – HI Fall relation
23. 30/03/20 K. Lutz - Intro to my Science 24 SHREG conclusion • More than 600 HI data cubes • Kinematic modelling has begun • Angular momentum – mass relation surprisingly scattered
24. 30/03/20 K. Lutz - Intro to my Science 25 MCX Bot et al. (2010)
25. 30/03/20 K. Lutz - Intro to my Science 26 MSX conclusion • IRAM proposal resubmitted with Caroline and Chris
26. 30/03/20 K. Lutz - Intro to my Science 28 CDS service work • Virtual Observatory Tutorials – Python – Standard VO applications • Providing a scientists viewpoints on: – Radio data archives – Science Platforms
