An Error Analysis of the Geometric Baade-Wesselink Method
Massimo Marengo, Margarita Karovska, Dimitar D. Sasselov +1
We derive an analytic solution for the minimization problem in the geometric Baade-Wesselink method. This solution allows deriving the distance and mean radius of a pulsating star…
Spatially Resolved Circumnuclear Dust in Centaurus A
Margarita Karovska, Massimo Marengo, Martin Elvis +6
In this paper we present results from our exploratory mid-IR study of Centaurus A circumnuclear environment using high-angular resolution imaging at the Magellan 6.5m telescope wit…
Molecular Hydrogen Emission Lines in Far Ultraviolet Spectroscopic Explorer Observations of Mira B
Brian E. Wood, Margarita Karovska
We present new Far Ultraviolet Spectroscopic Explorer (FUSE) observations of Mira A's wind-accreting companion star, Mira B. We find that the strongest lines in the FUSE spectrum a…
Theoretical Limb Darkening for Classical Cepheids: II. Corrections for the Geometric Baade-Wesselink Method
Massimo Marengo, Margarita Karovska, Dimitar D. Sasselov +2
The geometric Baade-Wesselink method is one of the most promising techniques for obtaining a better calibration of the Cepheid period-luminosity relation by means of interferometri…
Distances on Cosmological Scales with VLTI
Margarita Karovska, Martin Elvis, Massimo Marengo
We present here a new method using interferometric measurements of quasars, that allows the determination of direct geometrical distances on cosmic scales. Quasar Broad Emission Li…
