Line-of-sight shear in SLACS strong lenses II: validation tests with an extended sample
Natalie B. Hogg, Daniel P. Johnson, Anowar J. Shajib +1
The paper extends measurements of line‑of‑sight shear in 45 SLACS strong‑lens systems, finding a mean shear magnitude of about 0.11 and showing that unusually large LOS shears are…
Line-of-sight shear in SLACS strong lenses I: shear and mass model parametrisations
Natalie B. Hogg, Daniel P. Johnson, Anowar J. Shajib +1
Inhomogeneities along the line of sight in strong gravitational lensing distort the images produced, in an effect called shear. If measurable, this shear may provide independent co…
Efficient ion re-acceleration in laboratory-produced interpenetrating collisionless shocks
W. Yao, I. Cohen, P. Suarez Gerona +20
Although the origin of cosmic rays (CRs) remains an open question, collisionless magnetized shock waves are widely regarded as key sites for particle acceleration. Recent theories…
Neutrino mass limits and decaying dark matter: background evolution versus perturbations
Thomas Montandon, Vivian Poulin, Thomas Rink +1
We revisit cosmological neutrino mass bounds when a fraction of dark matter is allowed to decay to massless dark radiation. By compensating the late-time increase in the matter den…
Les Houches on Dark Universe 2025: Elements of cosmology beyond FLRW
Pierre Fleury
Modern cosmology is based on the cosmological principle, which states that the Universe is statistically homogeneous and isotropic. When applied in its strict -- rather than statis…
JAXtronomy: A JAX port of lenstronomy
Alan Huang, Simon Birrer, Daniel Gilman +4
Gravitational lensing is a phenomenon where light bends around massive objects, resulting in distorted images seen by an observer. Studying gravitationally lensed systems provides…
