The Araucaria Project. Distances to Nine Galaxies Based on a Statistical Analysis of their Carbon Stars (JAGB Method)
Bartłomiej Zgirski, Grzegorz Pietrzyński, Wolfgang Gieren +13
Our work presents an independent calibration of the J-region Asymptotic Giant Branch (JAGB) method using Infrared Survey Facility (IRSF) photometric data and a custom luminosity fu…
The Araucaria Project: Deep near-infrared photometric maps of Local and Sculptor Group galaxies. I. Carina, Fornax, Sculptor
Paulina Karczmarek, Grzegorz Pietrzyński, Wolfgang Gieren +12
Deep near-infrared - and -band photometry of three Local Group dwarf spheroidal galaxies: Fornax, Carina, and Sculptor, is made available for the community. Until now, these…
Metallicities and ages for 35 star clusters and their surrounding fields in the Small Magellanic Cloud
W. Narloch, G. Pietrzyński, W. Gieren +13
In this work we study 35 stellar clusters in the Small Magellanic Cloud (SMC) in order to provide their mean metallicities and ages. We also provide mean metallicities of the field…
A distance determination to the Small Magellanic Cloud with an accuracy of better than 2 percent based on late-type eclipsing binary stars
Dariusz Graczyk, Grzegorz Pietrzynski, Ian B. Thompson +17
We present a new study of late-type eclipsing binary stars in the Small Magellanic Cloud (SMC) undertaken with the aim of improving the distance determination to this important gal…
Empirical calibration of the reddening maps in the Magellanic Clouds
Marek Gorski, Bartlomiej Zgirski, Grzegorz Pietrzynski +9
We present reddening maps of the Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC), based on color measurements of the red clump. Reddening values of our maps were obta…
A distance to the Large Magellanic Cloud that is precise to one per cent
G. Pietrzynski, D. Graczyk, A. Gallenne +19
In the era of precision cosmology, it is essential to empirically determine the Hubble constant with an accuracy of one per cent or better. At present, the uncertainty on this cons…
