Constraining reionization with persistent homology: a novel summary statistic for wide-field Lyman- emitter observations
Michael M. Wyatt, Nikolaos Triantafyllou, Steven R. Furlanetto +4
The spatial clustering of Lyman- emitters (LAEs) is one of the most promising observables for constraining reionization. In this work, we introduce persistent homology, a popula…
TILING I: Field-level Bayesian reconstruction of cosmological initial conditions during the epoch of reionization
Nikolaos Triantafyllou, Andrei Mesinger, Steven Murray +1
Reconstructing the initial conditions (ICs) of the matter field for an observed volume gives a complete picture of that region's temporal evolution. IC reconstruction is common at…
Searching for a signature of turnaround in galaxy clusters with convolutional neural networks
Nikolaos Triantafyllou, Giorgos Korkidis, Vasiliki Pavlidou +1
Galaxy clusters are important cosmological probes that have helped to establish the CDM paradigm as the standard model of cosmology. However, recent tensions between diff…
IXPE Observation of the Low-Synchrotron Peaked Blazar S4 0954+65 During An Optical-X-ray Flare
Pouya M. Kouch, Ioannis Liodakis, Francesco Fenu +134
The X-ray polarization observations made possible with the Imaging X-ray Polarimetry Explorer (IXPE) offer new ways of probing high-energy emission processes in astrophysical jets…
