The SIMPLIFI Survey: Polarization of Dense Filaments with SOFIA III. Relative orientations of antenna temperature gradients with the magnetic field in the DR21 molecular cloud
We investigate magnetohydrodynamic (MHD) turbulence in the DR21 molecular cloud using far infrared polarimetry from SOFIA HAWC+ and molecular spectroscopy from the Nobeyama 45~m telescope.Leviathan: a very massive, extended sub-millimetre galaxy spectroscopically confirmed at $\rm z = 4.05$
We present Leviathan, a sub-millimetre galaxy (SMG) spectroscopically confirmed at $z=4.051$ with JWST/NIRSpec.20,000 Rotation Periods in Nearby Open Clusters and Moving Groups from ZTF and ASAS-SN
Open clusters provide uniquely powerful laboratories for studying stellar evolution because their members share a common age and chemical composition.A MUSE Study of Stellar and Ionized-Gas Kinematics in Central Group Galaxies
Understanding gas accretion and feedback in low-mass galaxy groups bridges the gap between isolated ellipticals and cluster-dominant galaxies.The GLEAM 4-Jy (G4Jy) Sample: V. Broadband spectral analysis
The G4Jy Sample consists of 1,863 of the brightest sources in the southern sky, as selected at 151 MHz using the GaLactic and Extragalactic All-sky MWA (GLEAM) survey.Ionized Gas Kinematics and Star-forming Clumps in Extremely Metal-poor Galaxies
Extremely Metal Poor (XMP) galaxies are the least chemically evolved objects in the local Universe and provide important constraints on galaxy formation in low-metallicity environments.Searching for Dense Perturbers in Cold Dark Matter Simulations
Recently, several low-mass, dense perturbers have been inferred from astrophysical observations of gravitational lensing, stellar streams, and satellite galaxies.J-PLUS: Identifying Outlier Spectral Energy Distributions in the Fourth Data Release Using Unsupervised Machine Learning
The selection of candidates belonging to rare or underrepresented stellar populations, as well as novel objects, is essential for spectroscopic follow-up.Core-Collapse Supernova Rates in the Dark Energy Survey
Over its five-year campaign (2013-2017), the Dark Energy Survey (DES) supernova (SN) survey recorded 31,636 light curves.IMF-aware N-body forward modelling of membership selection functions for young open clusters
We present an IMF-aware N-body forward-modelling framework, in which the stellar initial mass function (IMF) is an explicit input, to quantify the membership selection functions of open clusters…Dynamical response of a protoplanetary disk to an FU Ori-type outburst
Episodic accretion events onto young stars can significantly change the global structure of their surrounding protoplanetary disks.Connecting galaxy structure, quenching, and halo environments during cosmic noon
The connection between galaxy structure, star formation activity, and large-scale environments provides important insights into the evolution of massive galaxies.The Next Generation Virgo Cluster Survey (NGVS). XXIX. Demography of Nuclear Star Clusters
Nuclear star clusters (NSCs) provide insights into processes shaping galaxy cores.Reading Between the Lines: How Much Information Remains After Fitting a Stellar Spectrum?
What if we could model 100% of a stellar spectrum?Upper bounds on the number of images produced by point-mass lenses at different distances
If a light source is sequentially lensed by $n$ intervening point-mass lenses at distinct distances, the number of isolated images for a generic source position cannot be greater than $2\cdot…Inferring the shapes of low-mass galaxies at $z>6$ from FIREbox$^{HR}$. Where are the disks?
The three-dimensional shapes of galaxies provide clues to their formation and evolution.Spiraling into the `snail' cluster MCXC J0157.4-0550
We present a deep Chandra (130 ks) study of a striking, tidally induced cold front in a subcluster merging with the galaxy cluster MCXC J0157.4-0550.Statistical Strong Lensing V. Inference with Microlensed Quasars
Microlensing of strongly lensed quasars provides direct information on the stellar component of lens galaxies, and can help break the degeneracy between the stellar initial mass function (IMF) and…Newly Identified Planetary Nebula Candidates in M31 using Deep-Learning Search of Hubble Space Telescope Images
The Hubble Space Telescope has imaged approximately a quarter of a billion stars in M31's disc, yet only slightly over a thousand planetary nebulae (PNe) are known, mostly from ground-based surveys.Forecasting the Resolvability of Stellar Velocity Dispersions in Ultra-faint Dwarf Galaxies
Ultra-faint dwarf galaxies (UFDs)---the smallest and most dark-matter dominated galactic systems---push the boundaries of our understanding of galaxy formation in the cold dark matter paradigm.
