The Effects of Lyman-Limit Systems on the Evolution and Observability of the Epoch of Reionization
Hemant Shukla, Garrelt Mellema, Ilian T. Iliev +1
We present the first large-scale, full radiative transfer simulations of the reionization of the intergalactic medium in the presence of Lyman-limit systems (LLSs). To illustrate t…
HI tomographic imaging of the Cosmic Dawn and Epoch of Reionization with SKA
Garrelt Mellema, León Koopmans, Hemant Shukla +3
We provide an overview of 21cm tomography of the Cosmic Dawn and Epoch of Reionization as possible with SKA-Low. We show why tomography is essential for studying CD/EoR and present…
GPU Acceleration of Image Convolution using Spatially-varying Kernel
Steven Hartung, Hemant Shukla, J. Patrick Miller +1
Image subtraction in astronomy is a tool for transient object discovery such as asteroids, extra-solar planets and supernovae. To match point spread functions (PSFs) between images…
Dense Ionized and Neutral Gas Surrounding Sgr A*
Hemant Shukla, Min S. Yun, N. Z. Scoville
We present high resolution H41a hydrogen recombination line observations of the 1.2' (3 pc) region surrounding Sgr A* at 92 GHz using the OVRO Millimeter Array with an angular reso…
Neutral Hydrogen in the Ringed Barred Galaxies NGC 1433 and NGC 6300
Stuart D. Ryder, Ronald J. Buta, Hector Toledo +3
We have made observations of the \ion{H}{1} in the southern ringed barred spiral galaxies NGC~1433 and NGC~6300 with the Australia Telescope Compact Array (ATCA), the main goal bei…
