All-Sky Faint DA White Dwarf Spectrophotometric Standards for Astrophysical Observatories: The Complete Sample

Tim Axelrod, Abhijit Saha, Thomas Matheson +14

Hot DA white dwarfs have fully radiative pure hydrogen atmospheres that are the least complicated to model. Pulsationally stable, they are fully characterized by their effective te…

Fifteen years of millimeter accuracy lunar laser ranging with APOLLO: dataset characterization

James B. R. Battat, Eric Adelberger, Nicholas R. Colmenares +7

We present data from the Apache Point Observatory Lunar Laser-ranging Operation (APOLLO) covering the 15-year span from April 2006 through the end of 2020. APOLLO measures the eart…

Using Elliptical Galaxy Kinematics to Compare of the Strength of Gravity in Cosmological Regions of Differing Gravitational Potential -- A First Look

Eske M. Pedersen, Christopher W. Stubbs

Various models of modified gravity invoke ``screening'' mechanisms that are sensitive to the value of the local gravitational potential. This could have observable consequences for…
