Linear C4H and cyclic c-C3H2, as small unsaturated hydrocarbons, are the key precursors to complex organic molecules and are critical components of the interstellar medium. We present on-the-fly mapping observations […]

HAT-P-70b Through The Eyes of MAROON-X: Constraining Elemental Abundances of Metals and Insights on Atmosphere Dynamics
Ultra-hot Jupiters (UHJs) are exceptional laboratories for studying planetary atmospheres under extreme irradiation conditions.
The Hubble Advanced Spectral Product (HASP) Program
The Hubble Advanced Spectral Products (HASP) program is designed to robustly coadd Cosmic Origins Spectrograph (COS) and Space Telescope Imaging Spectrograph (STIS) spectra within the Mikulski Archive for Space Telescopes […]
Spectrally And Spatially Resolved (sub)millimeter HCN-to-HCO+ Flux Ratios In Nearby Ultraluminous Infrared Galaxies
We present the results of our investigations of spectrally and spatially resolved (sub)millimeter HCN-to-HCO+ flux ratios at J=2-1, J=3-2, and/or J=4-3 in 18 nearby (z< 0.15) ultraluminous infrared galaxies (ULIRGs), […]
Life Is But a Stream: The Distribution Of Planetary Systems Along Stellar Streams And Their Properties
The majority of discovered exoplanets have been observed orbiting field stars as opposed to within a star cluster. To determine whether the lack of observed exoplanets in star clusters is […]
Results Of Ten Tears Of UCLA SETI Searches With The Green Bank Telescope
We have been conducting a search for narrowband radio signals with the L-band receiver (1.15-1.73 GHz) of the 100 m diameter Green Bank Telescope (Margot et al., 2023). So far, […]
From Gas To Stars Along The Spiral Wave: CO, HCN, And Star Formation Variations Across The Spiral Arms In NGC 4321 And M51
Molecular clouds form stars from the interstellar medium via gravitational collapse, following a sequence from low-density gas to high-density cores and eventually the formation of stars.
Finding Alien Worlds in Queensland — A Decade of MINERVA-Australis
Three decades ago, humanity entered the Exoplanet Era, with the discovery of the first planets orbiting other stars. Today, more than 6000 exoplanets are known – a tally recently bolstered […]
Phase-Space Crystallization in Galactic Globular Clusters: A Gaia-Based Metric and Implications for Technosignature Searches
We develop a model-independent framework to quantify phase-space “crystallization”, the degree of ordered radial and kinematic substructure, in 79 Galactic globular clusters using the Gaia EDR3-based membership catalogue of E. […]
Overview Of The New Hubble Spectroscopic Legacy Archive
The new Hubble Spectroscopic Legacy Archive (HSLA) provides coadded spectra of individual targets that have been observed with the Cosmic Origins Spectrograph (COS) and the Space Telescope Imaging Spectrograph (STIS) […]
