Homogenization of some low-cost control problems
Rajesh Mahadevan, T. Muthukumar
The aim of this article is to study the asymptotic behaviour of some low-cost control problems. These problems motivate the study of H-convergence with weakly convergingdata. An im…
Radio Variability in Seyfert Nuclei
C. G. Mundell, P. Ferruit, N. Nagar +1
Comparison of 8.4-GHz radio images of a sample of 11 early-type Seyfert galaxies with previous observations reveals possible variation in the nuclear radio flux density in 5 of the…
Static wormholes in vacuum for conformal gravity
Julio Oliva, David Tempo, Ricardo Troncoso
A static spherically symmetric wormhole solution for conformal gravity in vacuum is found. The solution possesses a single integration constant which determines the size of the nec…
The Leo IV dwarf spheroidal galaxy: color-magnitude diagram and pulsating stars
M. I. Moretti, M. Dall'Ora, V. Ripepi +10
We present the first V, B-V color-magnitude diagram of the Leo IV dwarf spheroidal galaxy, a faint Milky Way satellite recently discovered by the Sloan Digital Sky Survey. We have…
Extragalactic chemical abundances: do HII regions and young stars tell the same story? The case of the spiral galaxy NGC 300
Fabio Bresolin, Wolfgang Gieren, Rolf-Peter Kudritzki +3
(Abridged) We have obtained new spectrophotometric data for 28 HII regions in the spiral galaxy NGC 300, a member of the nearby Sculptor Group. The detection of auroral lines, incl…
The Araucaria Project. The Distance to the Sculptor Galaxy NGC 247 from Near-Infrared Photometry of Cepheid Variables
W. Gieren, G. Pietrzynski, I. Soszynski +7
We have obtained deep near-infrared images in J and K filters of four fields in the Sculptor Group spiral galaxy NGC 247 with the ESO VLT and ISAAC camera. For a sample of ten Ceph…
