A GPU-Accelerated Transient Detection Pipeline for DECam Time-Domain Surveys

Lei Hu, Tomás Cabrera, Antonella Palmese +8

We present a GPU-accelerated transient detection pipeline developed for time-domain surveys with the Dark Energy Camera (DECam). It enables real-time-capable image processing, inco…

Using 1991T/1999aa-like Type Ia Supernovae as Standardizable Candles

Jiawen Yang, Lifan Wang, Nicholas Suntzeff +13

We present the photometry of 16 91T/99aa-like Type Ia Supernovae (SNe Ia) observed by the Las Cumbres Observatory. We also use an additional set of 21 91T/99aa-like SNe Ia and 87 n…

Image Subtraction in Fourier Space

Lei Hu, Lifan Wang, Xingzhuo Chen +1

Image subtraction is essential for transient detection in time-domain astronomy. The point spread function (PSF), photometric scaling, and sky background generally vary with time a…
