VLT/FORS1 spectrophotometry of the first planetary nebula discovered in the Phoenix dwarf galaxy
Ivo Saviane, Katrina Exter, Yiannis Tsamis +2
Context: A planetary nebula (PN) candidate was discovered during FORS imaging of the Local Group dwarf galaxy Phoenix. Aims: Use this PN to complement abundances from red-giant sta…
Luminosity-Metallicity Relation for dIrr Galaxies in the Near-Infrared
Ivo Saviane, Valentin D. Ivanov, Enrico V. Held +4
(abridged) The present work is a first step to collect homogeneous abundances and near-infrared (NIR) luminosities for a sample of dwarf irregular (dIrr) galaxies, located in nearb…
A new red giant-based distance modulus of 13.3 Mpc to the Antennae galaxies and its consequences
Ivo Saviane, Yazan Momany, Gary S. Da Costa +2
The Antennae galaxies are the closest example of an ongoing major galaxy merger, and thereby represent a unique laboratory for furthering the understanding of the formation of exot…
The blue plume population in dwarf spheroidal galaxies: young stellar population or genuine blue stragglers?
Y. Momany, E. V. Held, I. Saviane +3
In the context of dwarf spheroidal galaxies it is hard to firmly disentangle a genuine Blue Stragglers (BSS) population from a normal young main (MS) sequence. This difficulty is p…
Dust observations of Comet 9P/Tempel 1 at the time of the Deep Impact
G. P. Tozzi, H. Boehnhardt, L. Kolokolova +15
On 4 July 2005 at 05:52 UT, the impactor of NASA's Deep Impact (DI) mission crashed into comet 9P/Tempel 1 with a velocity of about 10 km/s. The material ejected by the impact expa…
The distance to the Fornax Dwarf Spheroidal Galaxy
L. Rizzi, E. V. Held, I. Saviane +2
A large multicolour, wide-field photometric database of the Fornax dwarf spheroidal galaxy has been analysed using three different methods to provide revised distance estimates bas…
