Modeling Binary Lenses and Sources with the BAGLE Python Package
T. Dex Bhadra, J. R. Lu, Natasha S. Abrams +4
Gravitational microlensing is a powerful tool that can be used to find and measure the mass of isolated and dark compact objects. In many microlensing events, the lens, the source,…
Interstellar medium phases and abundances in the central parsec: A JWST MIRI/MRS view of the Galactic center
P. Vermot, A. Ciurlo, D. Rouan +8
We used newly obtained observations from the Mid-Infrared Instrument (MIRI) equipped with the Medium Resolution Spectrometer (MRS) aboard the James Webb Space Telescope (JWST) to e…
Maximizing science return by coordinating the survey strategies of Roman with Rubin, and other major facilities
R. A. Street, S. Gough-Kelly, C. Lam +13
[Abridged] The Nancy Grace Roman Space Telescope will be one of several flagship survey facilities operating over the next decade starting 2025. The deep near-IR imaging that…
Ground Layer Adaptive Optics for the W. M. Keck Observatory: Feasibility Study
J. R. Lu, M. Chun, S. M. Ammons +12
Ground-layer adaptive optics (GLAO) systems offer the possibility of improving the "seeing" of large ground-based telescopes and increasing the efficiency and sensitivity of observ…
A Slowly Precessing Disk in the Nucleus of M31 as the Feeding Mechanism for a Central Starburst
K. E. Lockhart, J. R. Lu, H. V. Peiris +3
We present a kinematic study of the nuclear stellar disk in M31 at infrared wavelengths using high spatial resolution integral field spectroscopy. The spatial resolution achieved,…
Keck Observations of the Galactic Center Source G2: Gas Cloud or Star?
K. Phifer, T. Do, L. Meyer +8
We present new observations and analysis of G2 - the intriguing red emission-line object which is quickly approaching the Galaxy's central black hole. The observations were obtaine…
The Shortest Known Period Star Orbiting our Galaxy's Supermassive Black Hole
L. Meyer, A. M. Ghez, R. Schoedel +7
Stars with short orbital periods at the center of our galaxy offer a powerful and unique probe of a supermassive black hole. Over the past 17 years, the W. M. Keck Observatory has…
A Disk of Young Stars at the Galactic Center as Determined by Individual Stellar Orbits
J. R. Lu, A. M. Ghez, S. D. Hornstein +3
We present new proper motions from the 10 m Keck telescopes for a puzzling population of massive, young stars located within 3.5" (0.14 pc) of the supermassive black hole at the Ga…
Measuring Distance and Properties of the Milky Way's Central Supermassive Black Hole with Stellar Orbits
A. M. Ghez, S. Salim, N. N. Weinberg +10
We report new precision measurements of the properties of our Galaxy's supermassive black hole. Based on astrometric (1995-2007) and radial velocity (2000-2007) measurements from t…
