It does not resolve the H0 tension, but does resolve matter power amplitude σ8 tension with galaxy survey data such as the Dark Energy Survey and Kilo-Degree Survey. Could it be a foreground effect? Its value is relatively stable for various band channels and sky masks, which argues that ...
role and complexity warrants a separate treatment. The questions about galaxy disk formation that a detailed analysis of the Milky Way may help answer are manyfold. What processes might determine galaxy disk structure? In particular, what processes set the exponential radial and vertical profiles seen...

Astrophysics.Epistemology.My dissertation developed an epistemology of data-driven astronomy and astrophysics (A&A). These are areas that have undergone very little philosophical work, despite being part of the fastest growing areas of science. The astronomical and astrophysical models being developed ...

To summarise, the disk-integrated polarimetric observables provide a valuable information on the field geometry. However, they capture only some part of the actual stellar magnetic field. Depending on the degree of local field intermittency, this part can be significant or represent a minor fraction...
2001). Nine square degree of the cluster, corresponding to ∼25Mpc2, have been observed in the UV with GALEX by Cortese et al. (2008b), and one extra field centered on the infalling region 1.6 Mpc south-west from the cluster core with a deep observation by Hammer et al. (2010a)...

We review the evidence for buried ice in the asteroid belt; specifically the questions around the so-called Main Belt Comets (MBCs). We summarise the evide
extrapolation of the models (e.g., quasi-linear vs. particle trapping). Electron-astrophysics missions must generate high-frequency and multi-point measurements of magnetic-field fluctuations and high-cadence measurements of electron distributions that will further our understanding of the degree to ...
