Reconstructing the primary CMB dipole
The observed dipole anisotropy of the cosmic microwave background (CMB)
temperature is much larger than the fluctuations observed on smaller scales and
is dominated by the kinematic contribution from the Doppler shifting of...
MOONS
MOONS is the new Multi-Object Optical and Near-infrared Spectrograph currently under construction for the Very Large Telescope (VLT) at ESO. This remarkable instrument combines, for the first time, the collecting power of an 8-m...
What it Takes to Measure Reionization with Fast Radio Bursts
Fast Radio Bursts (FRBs) are extra-galactic radio transients which exhibit a
distance-dependent dispersion of their signal, and thus can be used as
cosmological probes. In this article we, for the first time, apply...

The dust destruction timescales in the cores of clusters of galaxies are relatively short given their high central gas densities. However, substantial mid-infrared and sub-mm emission has been detected in many brightest cluster...
Optical Emission Line Nebulae in Galaxy Cluster Cores 1
S. L. Hamer, A. C. Edge, A. M. Swinbank, R. J. Wilman, F. Combes, P. Salomé, A. C. Fabian, C. S. Crawford, H. R. Russell, J. Hlavacek-Larrondo, B. McNamara, M. N. Bremer

We present an Integral Field Unit survey of 73 galaxy clusters and groups with the VIsible Multi Object Spectrograph (VIMOS) on VLT. We exploit the data to determine the H_alpha gas dynamics on kpc-scales to study the feedback...
How Do Magnetic Field Models Affect Astrophysical Limits on Light Axion-like Particles? An X-Ray Case Study with NGC 1275
Axion-like particles (ALPs) are a well-motivated extension to the standard
model of particle physics, and X-ray observations of cluster-hosted AGN
currently place the most stringent constraints on the ALP coupling...
Milky Way Satellite Census. IV. Constraints on Decaying Dark Matter from Observations of Milky Way Satellite Galaxies

We use a recent census of the Milky Way (MW) satellite galaxy population to
constrain the lifetime of particle dark matter (DM). We consider two-body
decaying dark matter (DDM) in which a heavy DM particle decays with...
First Constraints on Fuzzy Dark Matter from Lyman-α Forest Data and Hydrodynamical Simulations.
We present constraints on the masses of extremely light bosons dubbed fuzzy dark matter (FDM) from Lyman-α forest data. Extremely light bosons with a de Broglie wavelength of ∼1 kpc have been suggested as dark matter candidates...
The Local Group Mass in the Light of Gaia
High accuracy proper motions (PMs) of M31 and other Local Group satellites
have now been provided by the {\it Gaia} satellite. We revisit the Timing
Argument to compute the total mass $M$ of the Local Group from the orbit of...
New Constraints on the free-streaming of warm dark matter from intermediate and small scale Lyman-$α$ forest data

We present new measurements of the free-streaming of warm dark matter (WDM) from Lyman-α flux-power spectra. We use data from the medium resolution, intermediate redshift XQ-100 sample observed with the X-shooter spectrograph...

We propose a novel method to constrain turbulence and bulk motions in massive galaxies, galaxy groups, and clusters, exploring both simulations and observations. As emerged in the recent picture of top-down multiphase...
