Demonstration of an imaging technique for the measurement of PSF elongation caused by Atmospheric Dispersion

born/ProjectNewton 2 Dec 2021

We conclude that the addition of this type of diffraction mask can be valuable for measurements of atmospheric dispersion enabling high precision correction of this atmospheric effect on future instruments.

Orbiting globular clusters formed in dark matter mini-halos

eduardo-vitral/vitral_boldrini 2 Dec 2021

For clusters embedded in dark matter, we observe that the increment of mass from the extra dark component triggers a tidal radius growth that allows the mini-halo to work as a protective shield against tidal stripping, being itself stripped beforehand the stars.
