We have been intensively searching for PNe in nearby galaxies as one of the main objectives of the Local Group Census (LGC). The LGC is a narrow-band survey of the galaxies of the Local Group observable from La Palma, that was awarded observing time during period two of the ING Wide Field Imaging Survey programme (http://www.ing.iac.es/WFS/)

The measurement of coronal fields has in the past generally been restricted to the field strength or to only some of the components of the magnetic vector. We present here a technique for measuring the full magnetic vector near the base of the solar corona. As an application we report on observations of a developing active region with ongoing

One major difficulty in probing the nature of Lyman break galaxies (LBGs) at z ˜ 3 is the mismatch between our best images of LBGs, which are in the rest-UV, and the best images of local galaxies, which are in the rest-optical. To make direct comparisons between LBGs at z ˜ 3 and more local star-forming galaxies, we use HST/STIS to image a set of

Here we model a star forming factory in which the continuous creation of stars results in a highly concentrated, massive (globular cluster-like) stellar system. We show that under very general conditions a large-scale gravitational instability in the ISM, which triggers the collapse of a massive cloud, leads with the aid of a spontaneous first

In this paper, we present one method of numeric analysis for the star test with MatLab (ANPEM), applied to reflecting telescope. ANPEM finds the difference between centers of the images of the annulus obtained with a Newtonian telescope and a Ritchey Chretiene telescope with 14 and 211 cm of diameter respectively. ANPEM allows to identify

Multiband near-infrared images of 12 BL Lacertae objects were obtained with the 2.5 m telescope at the Las Campanas Observatory in order to determine the properties of their underlying host galaxies. Resolved emission was clearly detected in eight of the lowest redshift targets (up to z~0.3) and was modeled with a de Vaucouleurs r1/4 surface
