Galaxy-Galaxy Strong Lensing with U-Net (GGSL-UNet). I. Extracting 2-Dimensional Information from Multi-Band Images in Ground and Space Observations

Fucheng Zhong, Ruibiao Luo, Nicola R. Napolitano +6

We present a novel deep learning method to separately extract the two-dimensional flux information of the foreground galaxy (deflector) and background system (source) of Galaxy-Gal…

Exploring the effect of different cosmologies on the Epoch of Reionization 21-cm signal with POLAR

Anshuman Acharya, Qing-bo Ma, Sambit K. Giri +8

A detection of the 21-cm signal power spectrum from the Epoch of Reionization is imminent, thanks to consistent advancements from telescopes such as LOFAR, MWA, and HERA, along wit…

Inferring the density, spin-temperature and neutral-fraction fields of HI from its 21-cm brightness temperature field using machine learning

Bohdan Bidenko, Léon V. E. Koopmans, P. Daniel Meerburg

The 21-cm brightness-temperature field of neutral hydrogen during the Epoch of Reionization and Cosmic Dawn is a rich source of cosmological and astrophysical information, primaril…

Revised LOFAR upper limits on the 21-cm signal power spectrum at using Machine Learning and Gaussian Process Regression

Anshuman Acharya, Florent Mertens, Benedetta Ciardi +3

The use of Gaussian Process Regression (GPR) for foregrounds mitigation in data collected by the LOw-Frequency ARray (LOFAR) to measure the high-redshift 21-cm signal power spectru…

Euclid: The Early Release Observations Lens Search Experiment

J. A. Acevedo Barroso, C. M. O'Riordan, B. Clément +206

We investigated the ability of the Euclid telescope to detect galaxy-scale gravitational lenses. To do so, we performed a systematic visual inspection of the Eucl…

Ionospheric contributions to the excess power in high-redshift 21-cm power-spectrum observations with LOFAR

S. A. Brackenhoff, M. Mevius, L. V. E. Koopmans +9

The turbulent ionosphere causes phase shifts to incoming radio waves on a broad range of temporal and spatial scales. When an interferometer is not sufficiently calibrated for the…
