Microlensing extended stellar sources
H M Bryce, M A Hendry
We have developed a code to compute multi-colour microlensing lightcurves for extended sources, including the effects of limb darkening and photospheric star spots as a function of…
What can we learn from the fluxes of 1.2 Jy IRAS sample?
Stephane Rauzy, Martin Hendry
We present a new method for fitting peculiar velocity models to complete flux limited magnitude-redshifts catalogues, using the luminosity function of the sources as a distance ind…
Microlensing of Circumstellar Envelopes I. Simplified considerations for diagnosing radial and azimuthal flow
R. Ignace, M. A. Hendry
This paper presents first results on the line profile shapes from a circumstellar envelope in bulk motion as modified by a microlensing event. Only geometrically and optically thin…
One Arc Degree Core Substructure of the Virgo Cluster
A. R. Petrosian, V. G. Gurzadyan, M. A. Hendry +1
The results of an analysis of the substructure of 1 degree field galaxies of the Virgo cluster by means of the S-tree technique developed by Gurzadyan et al, are represented. The e…
Cepheids, supernovae and the value of
M. A. Hendry, S. M. Kanbur
The calibration of the Type Ia supernova distances using HST observations of Cepheid variables is discussed. A new maximum likelihood method of calibration is applied to derive the…
On improved Cepheid distance estimators
Shashi M. Kanbur, Martin A. Hendry
In this paper, we derive a physical argument for the existence of Period-luminosity and period-luminosity-colour relations at maximum light. We examine in detail a sample of Cephei…
