Constraining Lens Masses in Moderately to Highly Magnified Microlensing Events from Gaia
U. Pylypenko, Å. Wyrzykowski, P. J. MikoÅajczyk +57
Microlensing events provide a unique way to detect and measure the masses of isolated, non-luminous objects, particularly dark stellar remnants. Under certain conditions, it is pos…
A Combined TESS and Ground-based Study of Transit Timing Variations in HAT-P-16, TOI-1516 and TOI-2046 Systems
E. Sonbas, K. Kaplan, M. Tanriver +5
We present new results for the hot Jupiters HAT-P-16b, TOI-1516b, and TOI-2046b, based on photometric observations collected using both space- and ground-based facilities. Ground-b…
A high geometric albedo and small size of the Haumea cluster member (24835) 1995 SM55 from a stellar occultation and photometric observations
J. L. Ortiz, N. Morales, B. Sicardy +98
Trans-Neptunian objects (TNOs) are among the most ancient bodies of the solar system. Understanding their physical properties is key to constraining their origin and the evolution…
Deciphering the Physical Origin of GRB 240825A: A Long GRB Lacking a Bright Supernova
Rahul Gupta, Judith L. Racusin, R. Sanchez-Ramirez +52
We present a comprehensive multiwavelength analysis of GRB 240825A, a bright gamma-ray burst (GRB) detected by Fermi and Swift, with a prompt duration ( ~ 4 sec in 50-3…
Asteroid sizes determined with thermophysical model and stellar occultations
A. Choukroun, A. Marciniak, J. Äurech +165
Context. The sizes of many asteroids, especially slowly rotating, low-amplitude targets, remain poorly constrained due to selection effects. These biases limit the availability of…
X-ray and gamma-ray timing of GRB 180720B, GRB 181222B, GRB 211211A and GRB 220910A observed with Fermi and ASIM
M. D. Caballero-Garcia, E. Gogus, J. Navarro-Gonzalez +20
We present a timing study of the gamma and X-ray observations and analysis of a sample of bright gamma-ray bursts (GRBs; i.e. GRB 180720B, GRB 181222B, GRB 211211A and GRB 220910A)…
