Characterizing cool, neutral gas and ionized metals in the outskirts of low-z galaxy clusters [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2023
We present the first detection of cool, neutral gas in the outskirts of low-z galaxy clusters using a statistically significant sample of 3191 z ≈ 0.2 background quasar–foreground cluster pairs by cross-matching the Hubble Spectroscopic Legacy Archive ...

Flexible, integrated modeling of tokamak stability, transport, equilibrium, and pedestal physics [PDF]

open access: yesPhysics of Plasmas, 2023
The STEP (Stability, Transport, Equilibrium, and Pedestal) integrated-modeling tool has been developed in OMFIT to predict stable, tokamak equilibria self-consistently with core-transport and pedestal calculations.

Murchison Widefield Array detection of steep-spectrum, diffuse, non-thermal radio emission within Abell 1127 [PDF]

open access: yesPublications Astronomical Society of Australia, 2020
Diffuse, non-thermal emission in galaxy clusters is increasingly being detected in low-frequency radio surveys and images. We present a new diffuse, steep-spectrum, non-thermal radio source within the cluster Abell 1127 found in survey data from the ...

Monitoring of the radio galaxy M 87 during a low-emission state from 2012 to 2015 with MAGIC [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2020
M 87 is one of the closest (z = 0.004 36) extragalactic sources emitting at very high energies (VHE, E > 100 GeV). The aim of this work is to locate the region of the VHE gamma-ray emission and to describe the observed broad-band spectral energy ...

The inner structure of ΛCDM haloes – III. Universality and asymptotic slopes [PDF]

open access: yes, 2003
We investigate the mass profile of cold dark matter (ACDM) haloes using a suite of numerical simulations spanning five decades in halo mass, from dwarf galaxies to rich galaxy clusters.

Dark matter halo concentrations in the Wilkinson Microwave Anisotropy Probe year 5 cosmology [PDF]

open access: yes, 2008
We use a combination of three large N-body simulations to investigate the dependence of dark matter halo concentrations on halo mass and redshift in the Wilkinson Microwave Anisotropy Probe year 5 (WMAP5) cosmology.

CRIRES high-resolution near-infrared spectroscopy of diffuse interstellar band profiles. Detection of twelve new DIBs in the YJ band and an introduction of a combined ISM sight line and stellar analysis approach [PDF]

open access: yesAstronomy & Astrophysics, 2022
A high spectral resolution investigation of diffuse interstellar bands (DIBs) in the near-infrared ($YJ$ band) is conducted to test new methods, to confirm and improve existing parameters, and to search for new DIBs.

Slave voices and experiences in the later medieval Europe

open access: yesHistory Compass, Volume 21, Issue 10, October 2023., 2023
Abstract Late medieval slavery was profoundly entangled in urban life in particular. Cities all around the Mediterranean coast were implicated in the trade—although this article focuses on the Christian Mediterranean which was bound together by a general reliance on Roman law (alongside local customary laws and the canon law of the Church).

Substructures in cold dark matter haloes [PDF]

open access: yes, 2003
We analyse the properties of substructures within dark matter haloes (subhaloes) using a set of high-resolution numerical simulations of the formation of structure in a ACDM universe.
