Euclid preparation XXXII. Evaluating the weak-lensing cluster mass biases using the Three Hundred Project hydrodynamical simulations

Georges Meylan, Frédéric Courbin, Austin Chandler Peel

The photometric catalogue of galaxy clusters extracted from ESA Euclid data is expected to be very competitive for cosmological studies. Using dedicated hydrodynamical simulations, we present systematic analyses simulating the expected weak-lensing profile ...

Baryon acoustic oscillation theory and modelling systematics for the DESI 2024 results

Jiaxi Yu, Daniel Felipe Forero Sanchez

This paper provides a comprehensive overview of how fitting of baryon acoustic oscillations (BAO) is carried out within the upcoming Dark Energy Spectroscopic Instrument’s (DESI) 2024 results using its DR1 data set, and the associated systematic error budg ...

Dissipative magnetic structures and scales in small-scale dynamos

Salim Bennouna

Small-scale dynamos play important roles in modern astrophysics, especially on galactic and extragalactic scales. Owing to dynamo action, purely hydrodynamic Kolmogorov turbulence hardly exists and is often replaced by hydromagnetic turbulence. Understandi ...

Validation of 2D T e and n e measurements made with Helium imaging spectroscopy in the volume of the TCV divertor

Patrick Blanchard, Basil Duval, Holger Reimerdes, Christian Gabriel Theiler, Hugo De Oliveira, Cedric Kar-Wai Tsui, Nicola Offeddu, Filippo Bagnato, Lorenzo Martinelli, Sophie Danielle Angelica Gorno, Claudia Colandrea, Dmytry Mykytchuk, Artur Perek

Multi-spectral imaging of helium atomic emission (HeMSI) has been used to create 2D poloidal maps of T-e and ne in TCV's divertor. To achieve these measurements, TCV's MANTIS multispectral cameras (Perek et al 2019 Rev. Sci. Instrum. 90 123514) simultaneou ...

High Performance Computing for gravitational lens modeling: Single vs double precision on GPUs and CPUs

Christoph Ernst René Schäfer, Jean-Paul Richard Kneib, Markus Rexroth

Strong gravitational lensing is a powerful probe of cosmology and the dark matter distribution. Efficient lensing software is already a necessity to fully use its potential and the performance demands will only increase with the upcoming generation of tele ...

Ni3N as an Active Hydrogen Oxidation Reaction Catalyst in Alkaline Medium

Andreas Schueler, Josef Andreas Schuler, Xile Hu, Anna Krammer, Weiyan Ni

Hydroxide-exchange membrane fuel cells can potentially utilize platinum-group-metal (PGM)-free electrocatalysts, offering cost and scalability advantages over more developed proton-exchange membrane fuel cells. However, there is a lack of non-precious elec ...

Molecular gas in two companion cluster galaxies at z=1.2

Anand Stéphane Raichoor, Gianluca Castignani

Context. Probing both star formation history and evolution of distant cluster galaxies is essential to evaluate the effect of dense environment on shaping the galaxy properties we observe today. ...

The SDSS-IV extended Baryon Oscillation Spectroscopic Survey: selecting emission line galaxies using the Fisher discriminant

Xiaoqing Zhou, Jean-Paul Richard Kneib, Timothée Guy Olivier Delubac, Jian Wang, Anand Stéphane Raichoor

We present a new selection technique of producing spectroscopic target catalogues for massive spectroscopic surveys for cosmology. This work was conducted in the context of the extended Baryon Oscillation Spectroscopic Survey (eBOSS), which will use simila ...

Disentangling a group of lensed submm galaxies at z similar to 2.9

Jean-Paul Richard Kneib

MS 0451.6-0305 is a rich galaxy cluster whose strong lensing is particularly prominent at submm wavelengths. We combine new Submillimetre Common-User Bolometer Array (SCUBA)-2 data with imaging from Herschel Spectral and Photometric Imaging Receiver (SPIRE ...

THE ENVIRONMENTS OF STARBURST AND POST-STARBURST GALAXIES AT z=0.4-0.8

Pascale Jablonka

Post-starburst (E+A or k+a) spectra, characterized by their exceptionally strong Balmer lines in absorption and the lack of emission lines, belong to galaxies in which the star formation (SF) activity ended abruptly sometime during the past Gyr. We perform ...
