The star formation history of Seyfert 2 nuclei
- R. C. Fernandes, Q. Gu, France.
- Physics
- 25 August 2004
We present a study of the stellar populations in the central ∼200 pc of a large and homogeneous sample comprising 79 nearby galaxies, most of which are Seyfert 2s. The star formation history of these…
Near-infrared template spectra of normal galaxies: k-corrections, galaxy models and stellar populations
- F. Mannucci, F. Basile, Chile.
- Physics
- 26 April 2001
We have observed 28 local galaxies in the wavelength range between 1 and 2.4 μm in order to define template spectra of the normal galaxies along the Hubble sequence. Five galaxies per morphological…
Infall, Outflow, Rotation, and Turbulent Motions of Dense Gas within NGC 1333 IRAS 4
- J. Francesco, P. Myers, Chile.
- Physics
- 1 August 2001
Millimeter wavelength observations are presented of NGC 1333 IRAS 4, a group of highly embedded young stellar objects in Perseus, that reveal motions of infall, outflow, rotation, and turbulence in…
The first ALMA view of IRAS 16293-2422 - Direct detection of infall onto source B and high-resolution kinematics of source A
Aims: In this paper, we focus on the kinematical properties of a proto-binaryto study the infall and rotation of gas towards its two protostellarcomponents. Methods: We present ALMA Science…
The first appearance of the red sequence of galaxies in proto-clusters at 2 <~ z <~ 3
We explore the evolved galaxy population in the proto-clusters around four high-z radio galaxies at 2 ≤ z ≤ 3 based on wide-field near-infrared (NIR) imaging. Three of the four fields are known…
Carbon and oxygen in H II regions of the Magellanic Clouds: abundance discrepancy and chemical evolution
- L. Cipriano, G. Dom'inguez-Guzm'an, Usa
- Physics
- 3 February 2017
We present C and O abundances in the Magellanic Clouds derived from deep spectra of HII regions. The data have been taken with the Ultraviolet-Visual Echelle Spectrograph at the 8.2-m VLT. The sample…
Large-scale study of the ngc 1399 globular cluster system in fornax
- L. Bassino, F. Faifer, H Germany
- Physics
- 14 March 2006
We present a Washington C and Kron-Cousins R photometric study of the globular cluster system of NGC 1399, the central galaxy of the Fornax cluster. A large areal coverage of 1 square degree around…
Direct evidence of a sub-stellar companion around CT Chamaeleontis
- T. Schmidt, R. Neuhauser, H. Sternwarte
- Physics
- 16 September 2008
Aims. In our ongoing search for close and faint companions around T Tauri stars in the Chamaeleon star-forming region, we here present observations of a new common proper motion companion to the…
A new constraint on the time dependence of the proton-to-electron mass ratio - Analysis of the Q 0347-383 and Q 0405-443 spectra
- A. Ivanchik, P. Petitjean, Chile.
- Physics
- 7 July 2005
A new limit on the possible cosmological variation of the proton-to-electron mass ratio $\mu=m_{\rm p}/m_{\rm e}$ is estimated by measuring wavelengths of H 2 lines of Lyman and Werner bands from two…
Detection of two power-law tails in the probability distribution functions of massive GMCs
- N. Schneider, S. Bontemps, U. Exeter
- Physics
- 31 July 2015
We report the novel detection of complex high-column density tails in the probability distribution functions (PDFs) for three high-mass star-forming regions (CepOB3, MonR2, NGC6334), obtained from…
