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…

Implications of distance duality violation for the tension and evolving dark energy
Elsa M. Teixeira, William Giarè, Natalie B. Hogg +3
We investigate whether a violation of the distance duality relation (DDR), , connecting the angular diameter and luminosity distances, can explain the Hubb…
