Infrared Lightcurves of Near Earth Objects
Joseph L. Hora, Amir Siraj, Michael Mommert +9
We present lightcurves and derive periods and amplitudes for a subset of 38 near earth objects (NEOs) observed at 4.5 microns with the IRAC camera on the the Spitzer Space Telescop…
Multiwavelength Light Curves of Two Remarkable Sagittarius A* Flares
G. G. Fazio, J. L. Hora, G. Witzel +13
Sgr A*, the supermassive black hole (SMBH) at the center of our Milky Way Galaxy, is known to be a variable source of X-ray, near-infrared (NIR), and submillimeter (submm) radiatio…
Variability Timescale and Spectral Index of Sgr A* in the Near Infrared: Approximate Bayesian Computation Analysis of the Variability of the Closest Supermassive Black Hole
G. Witzel, G. Martinez, J. Hora +16
Sagittarius A* (Sgr A*) is the variable radio, near-infrared (NIR), and X-ray source associated with accretion onto the Galactic center black hole. We present an analysis of the mo…
Unraveling the Spectral Energy Distributions of Clustered YSOs
Juan R. Martínez-Galarza, Pavlos Protopapas, Howard A. Smith +1
Stars form in clustered environments, but how they form when the available resources are shared is still not well understood. A related question is whether the IMF is in fact unive…
Filamentary Fragmentation and Accretion in High-Mass Star-Forming Molecular Clouds
Xing Lu, Qizhou Zhang, Hauyu Baobab Liu +7
Filamentary structures are ubiquitous in high-mass star-forming molecular clouds. Their relation with high-mass star formation is still to be understood. Here we report interferome…
The AGN Luminosity Fraction in Merging Galaxies
Jeremy Dietrich, Aaron S. Weiner, Matthew L. N. Ashby +7
Galaxy mergers are key events in galaxy evolution, often causing massive starbursts and fueling active galactic nuclei (AGN). In these highly dynamic systems, it is not yet precise…
