The Milky Way Laboratory is a research group at the University of Connecticut that specializes in using our home Galaxy as a laboratory for understanding star formation throughout the cosmos. Read about our research, meet the team, and see where we are featured in the media. For a broad-level public overview of our work, check out our latest news items!

We are an open source research group. The Milky Way Lab freely shares our code: Milky Way Laboratory on GitHub and have many repositories on the Central Molecular Zone Github. Our recent 3D CMZ project has its own dedicated 3D CMZ website with paper links, code, data, a worldwide telescope tour, and a cool 3D viewer. Our CMZoom data is publicly available at the CMZoom Dataverse.

The Milky Way Laboratory was founded by Prof. / Dr. Cara Battersby, who is an associate professor of physics at the University of Connecticut, specializing in observational astrophysics. Prof. Battersby studies how stars are born in our Galaxy’s Central Molecular Zone (CMZ) by combining large observational surveys and numerical simulations. Prof. Battersby has authored over 100 publications and given over 70 invited research presentations. Read more about her research, team, and accolades. She is not very media-social, but you can sometimes find her on bluesky.

  • PRIMA General Observer Science Book Volume 2 November 14, 2025
    This PRobe far-Infrared Mission for Astrophysics (PRIMA) mission concept is a proposed mission to NASA's Astrophysics Probe Explorer (APEX) call. The concept features a cryogenically cooled 1.8 m diameter telescope, and is designed to carry two science instruments covering the 24 to 264 $μ$m wavelength range: an imaging polarimeter (PRIMAger) and a spectrometer (FIRESS). The […]

  • ALMAGAL V. Relations between the core populations and the parent clump physical properties November 13, 2025
    Context. The fragmentation of massive molecular clumps into smaller, potentially star-forming cores plays a key role in the processes of high-mass star formation. The ALMAGAL project offers high-resolution data to investigate these processes across various evolutionary stages in the Galactic plane. Aims. This study aims at correlating the fragmentation properties of massive clumps, obtained from […]

  • Investigating the Role of Protostellar Variability with PRIMA Using Monte Carlo Simulations November 3, 2025
    Evidence suggests that protostellar outbursts likely play a critical role in the stellar mass assembly process, but the extent of this contribution is not well understood. Using the proposed observing program of PRIMA, a concept far-IR observatory (PRIMA GO Case #43 in Moullet et al. 2023), we examine the probe's ability to unambiguously determine whether […]

  • ALMAGAL VIII. Cataloging Hierarchical Mass Structure from Cores to Clumps across the Galactic Disk October 14, 2025
    Investigating the multi-scale fragmentation of dense clumps into compact cores is essential for understanding the processes that govern the initial distribution of mass in stellar clusters and how high-mass stars ($>8~M_{\odot}$) form. We present a catalog of the hierarchical continuum structure from 904 clumps observed in the ALMAGAL program, a high resolution ($0.15-0.8$\arcsec) 1.38 mm […]

  • The Colors of Ices: Measuring ice column density through photometry September 30, 2025
    Ices imprint strong absorption features in the near- and mid-infrared, but until recently they have been studied almost exclusively with spectroscopy toward small samples of bright sources. We show that JWST photometry alone can reveal and quantify interstellar ices and present a new open-source modeling tool, icemodels, to produce synthetic photometry of ices based on […]

  • Mapping CO Ice in a Star-Forming Filament in the 3 kpc Arm with JWST September 26, 2025
    CO gas emission is a fundamental tool for measuring column density, but in cold, dark clouds, much of the CO is locked away in ice. We present JWST results from observations of a star forming filament (G0.342+0.024) that that appears to be associated with the 3 kpc arm. This filament is backlit by the Galactic […]

  • JWST's first view of the most vigorously star-forming cloud in the Galactic center -- Sagittarius B2 September 15, 2025
    We report JWST NIRCAM and MIRI observations of Sgr B2, the most active site of star formation in the Galaxy. These observations, using 14 filters spanning 1.5 to 25 microns, have revealed a multilayered and highly structured cloud that contains both a revealed, low-extinction and hidden, high-extinction population of massive stars. JWST has detected new […]

  • The Far-Infrared Enhanced Survey Spectrometer (FIRESS) for PRIMA: Science Drivers September 1, 2025
    We present the science drivers for the Far-Infrared Enhanced Survey Spectrometer (FIRESS), one of two science instrument on the PRobe Infrared Mission for Astrophysics (PRIMA). FIRESS is designed to meet science objectives in the areas of the origins of planetary atmospheres, the co-evolution of galaxies and supermassive black holes, and the buildup of heavy elements […]
