A Test for the Origin of Quasar Redshifts
Piotr Popowski, Wolfgang Weinzierl
It is commonly accepted that quasar redshifts have a cosmological character and that most of the quasars are at Gigaparsec distances. However, there are some cases where several qu…
The MACHO Project Large Magellanic Cloud Variable Star Inventory. XIII. Fourier Parameters for the First Overtone RR Lyrae Variables and the LMC Distance
C. Alcock, D. R. Alves, T. S. Axelrod +21
Fourier coefficents have been derived for the and light curves of 785 overtone RR Lyrae variables in 16 MACHO fields near the bar of the LMC. The and coef…
The MACHO Project Large Magellanic Cloud variable star inventory. XI. Frequency analysis of the fundamental mode RR Lyrae stars
C. Alcock, D. R. Alves, A. Becker +20
We have frequency analyzed 6391 variables classified earlier as fundamental mode RR Lyrae (RR0) stars in the MACHO database on the Large Magellanic Cloud (LMC). The overwhelming ma…
Recent Microlensing Results from the MACHO Project
P. Popowski, C. A. Nelson, D. P. Bennett +19
We describe a few recent microlensing results from the MACHO Collaboration. The aim of the MACHO Project was the identification and quantitative description of dark and luminous ma…
The Large-Scale Extinction Map of the Galactic Bulge from the MACHO Project Photometry
Piotr Popowski, Kem Cook, Andrew Becker
We present a (V-R)-based reddening map of about 43 square degrees of the Galactic bulge/bar. The map is constructed using template image photometry from the MACHO microlensing surv…
