Alignment of galaxies relative to their local environment in SDSS-DR8
A. Hirv, J. Pelt, E. Saar +4
We study the alignment of galaxies relative to their local environment in SDSS-DR8 and, using these data, we discuss evolution scenarios for different types of galaxies. We defined…

Towards the automatic estimation of gravitational lenses' time delays
A. Hirv, N. Olspert, J. Pelt
Estimation of time delays from a noisy and gapped data is one of the simplest data analysis problems in astronomy by its formulation. But as history of real experiments show, the w…

Estimation of time delays from two blended light curves of gravitational lenses
A. Hirv, T. Eenmäe, L. J. Liivamägi +1
Long time photometric monitoring programs of gravitational lens systems are often carried on using modest equipment. The resolution of such observations is limited and some of the…
