TangoSIDM Project: is the stellar mass Tully-Fisher relation consistent with SIDM?

Self-interacting dark matter (SIDM) has the potential to significantly influence galaxy formation in comparison to the cold, collisionless dark matter paradigm (CDM), resulting in observable effects. This study aims to elucidate this influence and to demon ...

The Pristine Inner Galaxy Survey (PIGS): XI. Revealing the chemical evolution of the interacting Sagittarius dwarf galaxy

Pascale Jablonka

Context. The Sagittarius dwarf spheroidal galaxy (Sgr dSph) is a satellite orbiting the Milky Way that has experienced multiple stripping events due to tidal interactions with our Galaxy. Its accretion history has led to a distinct stellar overdensity, whi ...

An Indication of Gas Inflow in Clumpy Star-forming Galaxies near z ∼ 1: Lower Gas-phase Metallicities in Clumpy Galaxies Compared to Nonclumpy Galaxies

Pascale Jablonka

Despite the ubiquity of clumpy star-forming galaxies at high-redshift, the origin of clumps are still largely unconstrained due to the limited observations that can validate the mechanisms for clump formation. We postulate that if clumps form due to the ac ...

Exploiting the diversity of modeling methods to probe systematic biases in strong lensing analyses

Aymeric Alexandre Galan

Challenges inherent to high-resolution and high signal-to-noise data as well as model degeneracies can cause systematic biases in analyses of strong lens systems. In the past decade, the number of lens modeling methods has significantly increased, from pur ...

Weyl-invariant Einstein-Cartan gravity: unifying the strong CP and hierarchy puzzles

Mikhail Chapochnikov

We show that the minimal Weyl-invariant Einstein-Cartan gravity in combination with the Standard Model of particle physics contains just one extra scalar degree of freedom (in addition to the graviton and the Standard Model fields) with the properties of a ...

Euclid preparation LI. Forecasting the recovery of galaxy physical properties and their relations with template-fitting and machine-learning methods

Georges Meylan, Frédéric Courbin

Euclid will collect an enormous amount of data during the mission’s lifetime, observing billions of galaxies in the extragalactic sky. Along with traditional template-fitting methods, numerous machine learning (ML) algorithms have been presented for comput ...

Resistively controlled primordial magnetic turbulence decay

Andrii Neronov

Context. Magnetic fields generated in the early Universe undergo turbulent decay during the radiation-dominated era. The decay is governed by a decay exponent and a decay time. It has been argued that the latter is prolonged by magnetic reconnection, which ...

Prospects for detecting the circum- and intergalactic medium in X-ray absorption using the extended intracluster medium as a backlight

Yannick Michael Bahé

The warm-hot plasma in cosmic web filaments is thought to comprise a large fraction of the gas in the local Universe. So far, the search for this gas has focused on mapping its emission, or detecting its absorption signatures against bright, point-like sou ...

Complete field-induced spectral response of the spin-1/2 triangular-lattice antiferromagnet CsYbSe2

Andreas Martin Läuchli Herzig, Bruce Normand

Fifty years after Anderson's resonating valence-bond proposal, the spin-1/2 triangular-lattice Heisenberg antiferromagnet (TLHAF) remains the ultimate platform to explore highly entangled quantum spin states in proximity to magnetic order. Yb-based delafos ...

Synergistic interactions between PtRu catalyst and nitrogen-doped carbon support boost hydrogen oxidation

Andreas Schueler, Jeremy Luterbacher, Xile Hu, Anna Krammer, Weiyan Ni, Josephine Lederballe Meibom, Lichen Bai, Miyeon Chang, Seunghwa Lee, Songlan Sun, Seongmin Jin, Wenchao Ma, Yiwei Zheng

Hydroxide exchange membrane fuel cell (HEMFC) is a potentially cost-effective energy conversion technology. However, current state-of-the-art HEMFCs require a high loading of platinum-group-metal (PGM) catalysts, especially for the hydrogen oxidation react ...

Dark Energy Survey Year 3 results: Cosmological constraints from galaxy clustering and weak lensing

Jonathan Andrew Blazek

We present the first cosmology results from large-scale structure using the full 5000 deg(2) of imaging data from the Dark Energy Survey (DES) Data Release 1. We perform an analysis of large-scale structure combining three two-point correlation functions ( ...

Euclid: Forecast constraints on consistency tests of the ?CDM model

Georges Meylan, Frédéric Courbin

Context. The standard cosmological model is based on the fundamental assumptions of a spatially homogeneous and isotropic universe on large scales. An observational detection of a violation of these assumptions at any redshift would immediately indicate th ...
