From local chemistry to galactic evolution: unlocking the power of interstellar isotopes with ALMA2040
Molecular isotopic ratios provide a unique window into the chemical evolution of the interstellar medium, linking stellar nucleosynthesis and Galactic chemical evolution to the physical and chemical…ALMA2040: The High-Redshift Circumgalactic Medium. Imaging the fueling and feedback of galaxies in the early universe
Galaxies do not form in isolation, but rather as part of a wider interconnected web mediated at their interface by an extended gaseous atmosphere - the Circum-Galactic Medium (CGM).Frontiers of chemical complexity in the interstellar medium: unveiling the cosmic origins of life
The interstellar medium (ISM) contains a rich molecular inventory that provides a unique window into the chemistry operating during star and planet formation and its connection to prebiotic chemistry.From Scaling Relations to Physical Laws: Constraining the Physics of Star Formation Across Local Galaxies
The conversion of cold dense gas, traced by molecular line emission, into stars remains one of the fundamental unsolved problems in galaxy evolution.Star Formation across the Galaxy
Star formation is both a multi-scale and highly dynamic process.Intermediate- and high-resolution optical spectroscopy on the nascent planetary nebula Vy 2-2: Evidence of binary-star evolution
Planetary nebulae (PNe) tend to show spectacular non-spherical shapes whose origin is not fully understood.Disentangling Multi-epoch Single-lined Binary Star Spectra to Reveal Interstellar Medium Features via MCMC
Diffuse Interstellar Bands (DIBs) are interstellar absorption features with unidentified carriers in the optical and near-infrared spectra.Multi-wavelength Polarization as a Probe of Planet Formation
Polarization reveals details of circumstellar disks that are not readily available from total intensity observations.The Radius-Luminosity Relationship for Active Galactic Nuclei with Hierarchical Bayesian Reverberation Mapping
Reverberation mapping of active galactic nuclei uses the time taken for variability to travel through the system as a measure of system size, with this size being used to inform estimates of the…A Comprehensive AGN Inventory for the Dwarf-Dominated RESOLVE and ECO Surveys: Mass-Dependent AGN Types and Occupation Fractions
We catalog Active Galactic Nuclei (AGN) in the volume- and mass-limited RESOLVE and ECO surveys using (i) the BPT plot with standard and alternate demarcations, (ii) the BPT plot and VO plots (using…The Mission Market: Flying NASA's Vetted, Unflown Science
Every year NASA validates more excellent science missions than it can afford to fly.Stellar Mass Census of $S^4G$ Local Bars
Bars are stellar structures commonly found in disk galaxies and important agents of secular evolution.Dark Matter in the Galaxy: Insights from the Dynamics of Stellar Streams
Dark matter constitutes most of the matter in the Universe, yet its fundamental nature and distribution remain poorly understood.ALMA2040: Mapping the Spatially Resolved Dust and Star Formation Physics Driving High-z Galaxy Assembly
Interstellar dust reprocesses approximately half of the starlight emitted across cosmic history.High-frequency water megamasers as precision probes of black holes, galaxies and cosmology: A case for a next-generation sub-mm/mm interferometer
Water megamasers in the circumnuclear disks of active galactic nuclei are among the most precise probes of supermassive black holes.A Sample of Thick-Disk Stars Hosting Hot Jupiters
We present a homogeneous analysis of 268 confirmed and candidate transiting hot-Jupiter host stars with 4800K < Teff < 6200K.Chemical Demographics of Star-forming Regions
Our understanding of complex organic chemistry during the formation of stars and planets is shaped by a handful of cherry-picked sources with bright molecular emission lines.Resolving the AGN Feeding and Feedback Cycle with ALMA2040
Understanding how supermassive black holes (SMBHs) grow and regulate the growth of their host galaxies requires tracing the cold molecular interstellar medium (ISM) throughout the full AGN…The environments forming stellar and planetary systems
How does a star's birth environment set the mass, angular momentum and chemical complexity delivered to its planet-forming disk, and thereby whether it builds planets, brown dwarfs or stellar…Observational Signatures of Kerr Black Hole Lensing
Gravitational lensing by rotating black holes is modeled, and the null geodesic equations in the strong field regime are integrated numerically.
