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.

  • 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 […]

  • Circum-nuclear eccentric gas flow in the Galactic Center revealed by ALMA CMZ Exploration Survey (ACES) June 13, 2025
    We analyze the CS (J=2-1) line cube from the internal data release obtained by the large-scale program "ALMA CMZ Exploration Survey (ACES)" to investigate the kinematic structure of the innermost $\sim 10$ pc region of the Galaxy, which contains the high-velocity compact cloud (HVCC) at $(l,b,v_{\rm lsr})\sim(+0^\circ.02,-0^\circ.02, 100 {\rm km~s}^{-1})$ (hereafter G0.02). The longitude-velocity diagram […]

  • ALMAGAL IV. Morphological comparison of molecular and thermal dust emission using the histogram of oriented gradients (HOG) method April 17, 2025
    The study of molecular line emission is crucial to unveil the kinematics and the physical conditions of gas in star-forming regions. Our aim is to quantify the reliability of using individual molecular transitions to derive physical properties of the bulk of the H2 gas, looking at morphological correlations in their overall integrated molecular line emission […]

  • The Galactic-Centre Arms inferred from ACES (ALMA CMZ Exploration Survey) April 4, 2025
    Analyzing longitude-velocity diagrams (LVDs) in the CS(J=2-1) and H13CN(J=1-0) molecular lines from the internal release data of the ALMA Central-Molecular-Zone Exploration Survey (ACES) and in the 13CO (J=1-0) line from the Nobeyama Galactic-Centre (GC) survey, we identify six GC Arms as prominent straight LV ridges. In addition to the currently known Arms I to IV, […]

  • Dual-band Unified Exploration of Three CMZ Clouds (DUET). Cloud-wide census of continuum sources showing low spectral indices March 31, 2025
    The Milky Way's Central Molecular Zone (CMZ) is measured to form stars 10 times less efficiently than in the Galactic disk, based on emission from high-mass stars. However, the CMZ's low-mass protostellar population, which accounts for most of the initial stellar mass budget and star formation rate (SFR), is poorly constrained observationally due to limited […]

  • Discovery of a Giant Molecular Cloud at the Midpoint of the Galactic Bar Dust Lanes: M4.7-0.8 March 18, 2025
    We present the detection of a previously unknown giant molecular cloud (GMC) located at the midpoint of the Galactic Bar Dust Lanes (M4.7--0.8), using spectral line observations taken with the Green Bank Telescope (GBT). This $\sim$60 pc long GMC is associated with accreting material that is transitioning from the quieter Galactic disk environment to the […]

  • ALMAGAL III. Compact source catalog: Fragmentation statistics and physical evolution of the core population March 7, 2025
    The mechanisms behind the fragmentation of high-mass dense clumps into compact star-forming cores are fundamental topics in current astrophysical research. The ALMAGAL survey provides the opportunity to study this process at an unprecedented level of detail and statistical significance, featuring high-angular resolution $1.38$ mm ALMA observations of $1013$ massive dense clumps at various Galactic locations.
