Seasonal variation of Saturn's Lyman-$\alpha$ brightness

Autor: Stephenson, P., Koskinen, T. T., Brown, Z., Quémerais, E., Lavvas, P., Moses, J. I., Sandel, B., Yelle, R.

We examine Saturn's non-auroral (dayglow) emissions at Lyman-$\alpha$ observed by the {Cassini/UVIS} instrument from 2004 until 2016, to constrain meridional and seasonal trends in the upper atmosphere. We separate viewing geometry effects from trend

An Algorithm to locate the centers of Baryon Acoustic Oscillations

Autor: Brown, Z., Mishtaku, G., Demina, R., Liu, Y., Popik, C.

Publikováno v: A&A 647, A196 (2021)

The cosmic structure formed from Baryon Acoustic Oscillations (BAO) in the early universe is imprinted in the galaxy distribution observable in large scale surveys, and is used as a standard ruler in contemporary cosmology. BAO are typically detected
