A New spectral stellar library for population synthesis
A new spectral stellar library designed to be included in population synthesis models is presented. The library, which has been obtained at the INT 2.5 m...
Stellar population synthesis models are crucial for the understanding of the large amount of data which is being gathered for galaxies at low and high redshift...
A new stellar library in the region of the CO index at 2.3 μm. New index definition and empirical fitting functions
Context: The analysis of unresolved stellar populations demands evolutionary synthesis models with realistic physical ingredients and extended wavelength...
A new step forward in realistic cluster lens mass modelling: analysis of Hubble Frontier Field Cluster Abell S1063 from joint lensing, X-ray, and galaxy kinematics data
We present a new method to simultaneously and self-consistently model the mass distribution of galaxy clusters that combines constraints from strong lensing...
A new technique for decoupling the host and nuclear spectra of type I AGNs using integral field spectroscopy
We have developed a new technique to decouple the spectra of the host and the nucleus of type I AGNs using integral field spectroscopy (IFS) data. The technique...
Double bars make up a significant fraction of barred galaxies. We propose a new formation scenario for double bars that involves tidal interactions. We...
A New View of the Dwarf Spheroidal Satellites of the Milky Way from VLT FLAMES: Where Are the Very Metal-poor Stars?
As part of the Dwarf galaxies Abundances and Radial-velocities Team (DART) program, we have measured the metallicities of a large sample of stars in four nearby...
A new VLA/e-MERLIN limit on central images in the gravitational lens system CLASS B1030+074
We present the new Very Large Array 22 GHz and extended Multi-Element Remote-Linked Interferometer Network 5 GHz observations of CLASS B1030+074, a two-image...
A newly identified galaxy group thanks to tidal streams of intragroup light
Context. In the accretion-driven growth scenario, part of the intracluster light is formed in the group environment. Aims: We report the serendipitous discovery...
