Temperature mediated albedo decline portends acceleration of North American glacier mass loss
Snow and ice albedo
The albedo data used in our study originates from the MODIS sensor on the Terra satellite. Terra is in a near-polar sun synchronous descending orbit and acquires data with the MODIS sensor over a spectral range of…

A Massive Yellow Supergiant in the Far Outer Disk of M31: Evidence for in Situ Massive Star Formation beyond the Optical Radius
While massive stars are known to shape galactic ecosystems, their formation has long been assumed to require the high-density environments of inner galactic disks. This paradigm is challenged by mounting evidence of young massive stars in…

Reidentification of Redshifts of SDSS Galaxies Overlapped with Galactic Objects
This work presents a catalog of reidentified redshifts of 853 galaxies for which the redshifts of overlapping foreground objects were registered in the Sloan Digital Sky Survey (SDSS) DR16 Database. We examined SDSS DR16 spectra of the candidates…
