We present a Bayesian population modeling method to analyze the abundance of galaxy clusters identified by the South Pole Telescope (SPT) with a simultaneous mass calibration using weak gravitational lensing data from the Dark Energy Survey (DES) and the Hubble Space Telescope (HST). We discuss and validate the modeling choices with a particular

Context. In modern Galactic astronomy, stellar spectroscopy plays a pivotal role in complementing large photometric and astrometric surveys and enabling deeper insights to be gained into the chemical evolution and chemo-dynamical mechanisms at play in the Milky Way and its satellites. Nonetheless, the use of different instruments and dedicated

Trans-Neptunian Objects (TNOs) harbor some of the most pristine materials in the Solar System. JWST observations of TNOs from Cycle 1's campaign of "Discovering the composition of the TNOs" (DisCo-TNOs; #2418) provided the first, broad infrared (IR; 0.9—5 μm) coverage of these small-bodies. Spectral analyses of the over 50 DisCo-TNOs targets

CXOU J110926.4‑650224 is a candidate transitional millisecond pulsar (tMSP) with X-ray and radio emission properties reminiscent of those observed in confirmed tMSPs in their X-ray 'subluminous' disc state. We present the results of observing campaigns that, for the first time, characterise the optical and near-infrared variability of this source

Approximately 15% of the near-Earth asteroid (NEA) population are estimated to be binary systems. 54 binaries have Arecibo radar observations; 2020 BX 12 is one of them. Discovered on January 27, 2020, by the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey at Mauna Loa Observatory, 2020 BX 12 has an absolute magnitude of 20.6 and an

We apply the barred Schwarzschild method developed by Tahmasebzadeh et al. (2022) to a barred S0 galaxy, NGC 4371, observed by IFU instruments from the TIMER and ATLAS3D projects. We construct the gravitational potential by combining a fixed black hole mass, a spherical dark matter halo, and stellar mass distribution deprojected from 3.6 μm S $^4$G
