The circumnuclear environment of the peculiar galaxy NGC 3310
Guillermo F. Hagele, Angeles I. Diaz, Monica V. Cardaci +2
Gas and star velocity dispersions have been derived for eight circumnuclear star-forming regions (CNSFRs) and the nucleus of the spiral galaxy NGC3310 using high resolution spectro…
The Dark Energy Equation of State using Alternative High-z Cosmic Tracers
M. Plionis, R. Terlevich, S. Basilakos +4
We propose to use alternative cosmic tracers to measure the dark energy equation of state and the matter content of the Universe [w(z) & Omega_m]. Our proposed method consists of t…
Evolution of the X-ray Luminosity in Young HII Galaxies
D. Rosa González, E. Terlevich, E. Jiménez Bailón +5
In an effort to understand the correlation between X-ray emission and present star formation rate (SFR), we obtained XMM-Newton data to estimate the X-ray luminosities of a sample…
On the derivation of dynamical masses of the stellar clusters in the circumnuclear region of NGC2903
Guillermo F. Hagele, Angeles I. Diaz, Monica V. Cardaci +2
(Abridged) Gas and star velocity dispersions have been derived for four circumnuclear star-forming regions (CNSFRs) and the nucleus of the spiral galaxy NGC2903 using high resoluti…
On the Early Evolution of Young Starbursts
Daniel Rosa-Gonzalez, Henrique Schmitt, Elena Terlevich +1
We studied the radio properties of very young massive regions of star formation in HII galaxies, with the aim of detecting episodes of recent star formation in an early phase of ev…
Alternative High-z Cosmic Tracers and the Dark Energy Equation of State
M. Plionis, R. Terlevich, S. Basilakos +4
We propose to use alternative cosmic tracers to measure the dark energy equation of state and the matter content of the Universe [w(z) & Ω_m]. Our proposed method consists of two c…
