Exploring the cosmic 21-cm signal from the Epoch of Reionisation using the Wavelet Scattering Transform
Bradley Greig, Yuan-Sen Ting, Alexander A. Kaurov
Detecting the cosmic 21-cm signal during the Epoch of Reionisation and Cosmic Dawn will reveal insights into the properties of the first galaxies and advance cosmological parameter…
Asymmetric Surface Brightness Structure of Caustic Crossing Arc in SDSS J1226+2152: A Case for Dark Matter Substructure
Liang Dai, Alexander A. Kaurov, Keren Sharon +6
We study the highly magnified arc SGAS J122651.3+215220 caused by a star-forming galaxy at crossing the lensing caustic cast by the galaxy cluster SDSS J1226+2152 ($z_l=…
Research and Development for HI Intensity Mapping
Zeeshan Ahmed, David Alonso, Mustafa A. Amin +51
Development of the hardware, data analysis, and simulation techniques for large compact radio arrays dedicated to mapping the 21 cm line of neutral hydrogen gas has proven to be mo…
Packed Ultra-wideband Mapping Array (PUMA): A Radio Telescope for Cosmology and Transients
Kevin Bandura, Emanuele Castorina, Liam Connor +23
PUMA is a proposal for an ultra-wideband, low-resolution and transit interferometric radio telescope operating at . Its design is driven by six science goal…
Highly Magnified Stars in Lensing Clusters: New Evidence in a Galaxy Lensed by MACS J0416.1-2403
Alexander A. Kaurov, Liang Dai, Tejaswi Venumadhav +2
We examine a caustic-straddling arc at in the field of the galaxy cluster MACS J0416.1-2403 () using archival multiband HST images and show that its surface bri…
Non-perturbative probability distribution function for cosmological counts in cells
Mikhail M. Ivanov, Alexander A. Kaurov, Sergey Sibiryakov
We present a non-perturbative calculation of the 1-point probability distribution function (PDF) for the spherically-averaged matter density field. The PDF is represented as a path…
