🆕✨My latest paper is on arXiv! We study the molecular gas ratio and how it depends on local conditions in nearby galaxy disks using multi-wavelength observations. New and astonishing MeerKAT HI observations from the PHANGS and MHONGOOSE collaborations. 🔍arxiv.org/abs/2407.01716

Presented my recent paper at @yerac2024 @YERAC_EU 📡

It feels great to see PHANGS-MeerKAT and LGLBS on one slide [Kristine Spekkens' Plenary Talk #IAUS392] @astronomy2024 @PHANGSteam

ALMA 📡 2/3 PI proposals and 8 co-I proposals got accepted 🥳 My PI ones were A-ranked & B-ranked

Our study is an important step in the statistical investigation of how local galaxy properties (stellar mass, star formation rate, or morphology) impact the conversion from atomic to molecular gas in nearby galaxies. Big thanks goes to all my collaborators, especially @astrojysun

We found a direct correlation between PDE and the star formation rate surface density (ΣSFR), supporting self-regulation models. We attribute the modest differences that we found compared to previous works to the effect of varying resolution and sensitivity (e.g. Figure 11)

We find that the molecular gas ratio (Rmol) correlates best with the dynamical equilibrium pressure, PDE, among potential drivers studied, with a median correlation coefficient of ⟨ρ⟩ = 0.89.

The molecular gas ratio (Rmol) encodes important information as to the evolution of the interstellar medium (ISM) in galaxies. We found that at > ~0.4 optical radii, atomic gas dominates over molecular gas among our studied galaxies. This varies however from galaxy to galaxy.

An example of how extended the HI disks are compared to their CO disks. We found that HI is detected out to 20 − 120 kpc in galactocentric radius. The typical radius at which ΣHI reaches 1 Msun pc^−2 is ≈ 22 kpc, which corresponds to 1−3 times the optical radius.

First figure shows how incredible the PHANGS-MeerKAT HI observations are:

Incredible week. On Monday my paper got accepted. On Tuesday Sebastian (Master student I co supervised) resubmitted a paper and it got accepted a few hours later. Yesterday I gave a summer research lecture for the REU and NAC summer students at NRAO and it felt incredible ✨🌌

@elthateng @UMDAstronomy Ooooff a few days late but congrats Eltha!! 🎉🥳🤩 When do you start your PostDoc?

PhDone!! 🥳 Ready for my next step -- moving to College Park and joining @UMDAstronomy as a postdoc 🙌

@anna_dignan congrats! 🤩 (the only mario kart related gif I could find haha)

my first proposal was accepted this morning! it was an itty bitty one but still!

Spent the first half of the week @GreenBankObserv for the annual @TheNRAO and GBO Postdoc Symposium!! We had a great time bonding, talking about science and careers, and touring the telescope 🤩✨📡

The PHANGS collaboration, led by MPIA astronomer Eva Schinnerer, released stunning infrared images of 19 nearby galaxies taken with the James Webb Space Telescope (JWST) today mpia.de/news/2024-phan…

hi all our phangs-jwst data processing paper is out on arxiv (under review). take home messages: 1) you can download the data from archive.stsci.edu/hlsp/phangs/ph… 2) our pipeline is easily python-installable: pip install pjpipe 3) paper: arxiv.org/abs/2401.15142 (1/12)

@LeoBurtscher Dankeschön !! ☺️

@AstroCosi Herzlichen Glückwunsch zum erfolgreich verteidigten Doktorat! :)

Two weeks ago I successfully defended my PhD thesis (Magna cum laude — Dr. Eibensteiner 😳) in Bonn Germany and now I’m in Charlottesville, Virginia starting my Jansky fellowship ☀️ it all happened so fast 💨 #PhDDone

Sorry, @Kuoru_ just discovered your Twitter account ☺️

Look what we found: A constant N2H+(1-0)-to-HCN(1-0) ratio on kiloparsec scales 🧐 With Maria Jesus Jiménez-Donaire's new data on NGC 6946 and with literature compilation of N2H+ and HCN observations arxiv.org/abs/2308.01342
