- Dynamical Accretion Flows -- ALMAGAL: Flows along filamentary structures
in high-mass star-forming clusters August 15, 2024We use data from the ALMA Evolutionary Study of High Mass Protocluster Formation in the Galaxy (ALMAGAL) survey to study 100 ALMAGAL regions at $\sim$ 1 arsecond resolution located between $\sim$ 2 and 6 kpc distance. Using ALMAGAL $\sim$ 1.3mm line and continuum data we estimate flow rates onto individual cores. We focus specifically on […]M. R. A. Wells
- SOFIA/FORCAST Galactic Center Source Catalog July 10, 2024The central regions of the Milky Way constitute a unique laboratory for a wide swath of astrophysical studies, consequently the inner $\sim$400 pc has been the target of numerous large surveys at all accessible wavelengths. In this paper we present a catalog of sources at 25 and 37 $\mu$m located within all of the regions […]Angela S. Cotera
- A broad linewidth, compact, millimeter-bright molecular emission line
source near the Galactic Center April 11, 2024A compact source, G0.02467-0.0727, was detected in ALMA \threemm observations in continuum and very broad line emission. The continuum emission has a spectral index $\alpha\approx3.3$, suggesting that the emission is from dust. The line emission is detected in several transitions of CS, SO, and SO$_2$ and exhibits a line width FWHM $\approx160$ \kms. The line […]Adam Ginsburg
- Magnetic field morphology and evolution in the Central Molecular Zone
and its effect on gas dynamics March 19, 2024The interstellar medium in the Milky Way's Central Molecular Zone (CMZ) is known to be strongly magnetised, but its large-scale morphology and impact on the gas dynamics are not well understood. We explore the impact and properties of magnetic fields in the CMZ using three-dimensional non-self gravitating magnetohydrodynamical simulations of gas flow in an external […]R. G. Tress
- Thermal Properties of the Hot Core Population in Sagittarius B2 Deep
South January 18, 2024We report the discovery of 9 new hot molecular cores in the Deep South (DS) region of Sagittarius B2 using Atacama Large Millimeter/submillimeter Array Band 6 observations. We measure the rotational temperature of CH$_3$OH and derive the physical conditions present within these cores and the hot core Sgr B2(S). The cores show heterogeneous temperature structure, […]Desmond Jeff
- CMZoom IV. Incipient High-Mass Star Formation Throughout the Central
Molecular Zone December 14, 2023In this work, we constrain the star-forming properties of all possible sites of incipient high-mass star formation in the Milky Way's Galactic Center. We identify dense structures using the CMZoom 1.3mm dust continuum catalog of objects with typical radii of $\sim$0.1pc, and measure their association with tracers of high-mass star formation. We incorporate compact emission […]H Perry Hatchfield
- PRIMA General Observer Science Book October 31, 2023PRIMA (The PRobe for-Infrared Mission for Astrophysics) is a concept for a far-infrared (IR) observatory. PRIMA features a cryogenically cooled 1.8 m diameter telescope and is designed to carry two science instruments enabling ultra-high sensitivity imaging and spectroscopic studies in the 24 to 235 microns wavelength range. The resulting observatory is a powerful survey and […]A. Moullet
- Far-Infrared Luminosity Bursts Trace Mass Accretion onto Protostars October 19, 2023Evidence abounds that young stellar objects undergo luminous bursts of intense accretion that are short compared to the time it takes to form a star. It remains unclear how much these events contribute to the main-sequence masses of the stars. We demonstrate the power of time-series far-infrared (far-IR) photometry to answer this question compared to […]William J. Fischer

What what, ya girl got tenure! 🎉🎉🎉
Thanks so much everyone for the congratulations, wowzers! Feeling the love 💕 Long week but finally time to celebrate
I've been seeing a lot of great posters with amazing styles and sometimes art, but this one speaks to my heart...if Daria's on twitter can someone please RT and tag?

We all LOVE to do lip service for better maternity leave policies in academia (and yes, let's work on that) but as a professor and mom of two, I can confidently state there's more to it.
Research doesn't take a pause during leave and we all need to STEP UP to support each other.
3. MEETINGS. just, like, any expectation that i can reliably attend regular meetings when I return from leave, because let’s be honest, when babe is so tiny I am still caring for them tons and working when I can between that, not when my calendar says so.
How about other folks? Academia is not like other jobs in a lot of ways, how can we help to support each other better?
