Photometric Mapping of Carbonaceous/Siliceous Dust and Water Ice in the ISM with JWST: Applications to the Dense Sightlines

The Astronomical Journal
We introduce a new photometric mapping method for the James Webb Space Telescope (JWST) to measure the spatial distribution of carbonaceous dust, siliceous dust, and water ice by using absorption features arising from the grains in the dense interstellar

Estimating the luminosities of protostars with limited infrared photometry

Monthly Notices of the Royal Astronomical Society
ABSTRACT The luminosities of protostars provide one of the only indirect methods of measuring their masses and mass accretion rates in their earliest stages of evolution. Accurate measurements of protostellar luminosities traditionally requires assembling complete spectral energy distributions (SEDs) from the near-infrared through ...

The Baryonic Tully–Fisher Relation. I. WISE/Spitzer Photometry

The Astronomical Journal
We present Wide-field Infrared Survey Explorer (WISE) W1 photometry of the Spitzer Photometry and Accurate Rotation Curves sample. The baseline of near-IR fluxes is established for use by stellar mass models, a key component to the baryonic Tully–Fisher ...

A Highly Magnetic Ultramassive White Dwarf with a 23 minute Rotation Period

The Astrophysical Journal
We present a physical characterization of Tsinghua University-Ma Huateng Telescope for Survey (TMTS) J00063798+3104160 (J0006), a rapidly rotating, ultramassive white dwarf (WD) identified in high-cadence light curves from the TMTS.

A High Incidence of Dusty Hα Emitters at z > 3 Among UltraVISTA Dropout Galaxies in COSMOS Revealed by JWST

The Astrophysical Journal
We have characterized 26 Spitzer/IRAC-selected sources from the SMUVS program that are undetected in the UltraVISTA DR5 H - and/or K _s -band images, covering 94 arcmin ^2 of the COSMOS field, which have deep multiwavelength JWST ...

A Holistic Exploration of the Potentially Recoverable Redshift Information of Stage IV Galaxy Surveys

The Astrophysical Journal
Extragalactic science and cosmology with Stage IV galaxy surveys will rely almost exclusively on redshift measurements derived solely from photometry, which are subject to systematic and statistical uncertainties with numerous analysis choices.

Dust-obscured Galaxies with Broken Power-law Spectral Energy Distributions Discovered by UNIONS

The Astrophysical Journal
We report on the spectral energy distributions (SEDs) of infrared (IR)-bright dust-obscured galaxies (DOGs) with ( i − [22]) _AB ≥ 7.0. Using photometry from the deep and wide Ultraviolet Near-Infrared Optical Northern Survey, combined with near-IR (NIR)
