Optical Variability of the Dwarf AGN NGC 4395 from the Transiting Exoplanet Survey Satellite
Colin J. Burke, Yue Shen, Yu-Ching Chen +4
We present optical light curves from the Transiting Exoplanet Survey Satellite (TESS) for the archetypical dwarf active galactic nucleus (AGN) in the nearby galaxy NGC 4395 hosting…
Dark Energy Survey Identification of A Low-Mass Active Galactic Nucleus at Redshift 0.823 from Optical Variability
Hengxiao Guo, Colin J. Burke, Xin Liu +56
We report the identification of a low-mass AGN, DES J02180430, in a redshift galaxy in the Dark Energy Survey (DES) Supernova field. We select DES J02180430 as an…
The Curious Case of PHL 293B: A Long-Lived Transient in a Metal-Poor Blue Compact Dwarf Galaxy
Colin J. Burke, Vivienne F. Baldassare, Xin Liu +51
We report on small-amplitude optical variability and recent dissipation of the unusually persistent broad emission lines in the blue compact dwarf galaxy PHL 293B. The galaxy's unu…
The LSST DESC Data Challenge 1: Generation and Analysis of Synthetic Images for Next Generation Surveys
F. Javier Sánchez, Chris W. Walter, Humna Awan +23
Data Challenge 1 (DC1) is the first synthetic dataset produced by the Rubin Observatory Legacy Survey of Space and Time (LSST) Dark Energy Science Collaboration (DESC). DC1 is desi…
Deblending and Classifying Astronomical Sources with Mask R-CNN Deep Learning
Colin J. Burke, Patrick D. Aleo, Yu-Ching Chen +4
We apply a new deep learning technique to detect, classify, and deblend sources in multi-band astronomical images. We train and evaluate the performance of an artificial neural net…
PhoSim-NIRCam: Photon-by-photon image simulations of the James Webb Space Telescope's Near-Infrared Camera
Colin J. Burke, John R. Peterson, Eiichi Egami +3
Recent instrumentation projects have allocated resources to develop codes for simulating astronomical images. Novel physics-based models are essential for understanding telescope,…
