Galaxy NGC 6822 from Near - Infrared Photometry of Cepheid Variables
We have measured near-infrared magnitudes in the J and K bands for 56 Cepheid variables in the Local Group galaxy NGC 6822 with well-determined periods and optical light curves in the V and I bands. Using the template light curve approach of Soszyński, Gieren and Pietrzyński, accurate mean magnitudes were obtained from these data which allowed us to determine with unprecedented accuracy the dis...
متن کاملA Cepheid Distance to Ngc 4603 in Centaurus
In an attempt to use Cepheid variables to determine the distance to the Centaurus cluster, we have obtained images of NGC 4603 with the Hubble Space Telescope for 9 epochs (totalling 24 orbits) over 14 months in the F555W filter and 2 epochs (totalling 6 orbits) in the F814W filter. This galaxy has been suggested to lie within the “Cen30” portion of the Centaurus cluster, which is concentrated ...
متن کاملA Revised Cepheid Distance to Ngc 4258 and a Test of the Distance Scale
In a previous paper (Maoz et al. 1999), we reported a Hubble Space Telescope (HST) Cepheid distance to the galaxy NGC 4258 obtained using the calibrations and methods then standard for the Key Project on the Extragalactic Distance Scale. Here, we reevaluate the Cepheid distance using the revised Key Project procedures described in Freedman et al. (2001). These revisions alter the zero points an...
متن کاملESI, a new method for the excellence measurement
Excellence Synergic Index (ESI) is a new method for the excellence measurement. This technique is a causal method. ESI method was developed for studying the relations and interaction of excellence criteria and organizational pathology. By “ESI”, it is possible to measure the performance excellence of any service enterprises, to diagnosis organizational pathos and to propose problem-solvin...
متن کاملThe Star Formation History of NGC 6822
Images of five fields in the Local Group dwarf irregular galaxy NGC 6822 obtained with the Hubble Space Telescope in the F555W and F814W filters are presented. Three of the fields lie mostly within the central bar of NGC 6822 where most of the sites of current star formation are concentrated while two other fields sample more of the outer regions of the galaxy. Photometry for the stars in these...
