easyspec: An open-source Python package for long-slit spectroscopy
Raniere de Menezes, Francesco Massaro, Michela Negro +3
In modern-day astronomy, near-infrared, optical, and ultraviolet spectroscopy are indispensable for studying a wide range of phenomena, from measuring black hole masses to analyzin…
Mitigating Polarization Leakage in Gas Pixel Detectors through Hybrid Machine Learning and Analytic Event Reconstruction
Nicoló Cibrario, Michela Negro, Raffaella Bonino +18
Spatially resolved polarization measurements of extended X-ray sources are expanding our understanding of the emission mechanisms and magnetic field properties involved. Such measu…
Performance evaluation of the high-voltage CMOS active pixel sensor AstroPix for gamma-ray space telescopes
Yusuke Suda, Regina Caputo, Amanda L. Steinhebel +14
AstroPix is a novel monolithic high-voltage CMOS active pixel sensor proposed for next generation medium-energy gamma-ray observatories like the All-sky Medium Energy Gamma-ray Obs…
Joint machine learning and analytic track reconstruction for X-ray polarimetry with gas pixel detectors
Nicoló Cibrario, Michela Negro, Nikita Moriakov +9
We present our study on the reconstruction of photoelectron tracks in gas pixel detectors used for astrophysical X-ray polarimetry. Our work aims to maximize the performance of con…
Polarisation Leakage due to Errors in Track Reconstruction in Gas Pixel Detectors
N. Bucciantini, N. Di Lalla, R. W. R. Romani +5
X-ray polarimetry, based on Gas Pixel Detectors (GPDs), have reached a high level of maturity with the Imaging X-ray Polarimeter Explorer (IXPE) leading to the first ever spatially…
AstroPix: CMOS pixels in space
Amanda L. Steinhebel, Regina Caputo, Henrike Fleischhack +13
Space-based gamma-ray telescopes such as the Fermi Large Area Telescope have used single sided silicon strip detectors to measure the position of charged particles produced by inci…
