High Frequency Peaker (HFP) radio sources are an extreme class of active galactic nuclei whose nature has not been fully understood yet. They are compact...
We present a sample of sources with convex radio spectra peaking at frequencies above a few GHz, known as ``High Frequency Peakers" (HFPs). A ``bright" sample...
High Gas Fraction in a CO-detected Main-sequence Galaxy at z > 3
We report NOrthern Extended Millimetre Array (NOEMA) observations of warm molecular gas traced by CO(5 ‑ 4) in a z∼ 3.2 gas-rich main-sequence (MS) galaxy...
High redshift galaxies & Lyman Alpha Emitters through gravitational lensing
The techniques and some preliminary results on the study of the luminosity function (LF) of Lyman Alpha Emitters (LAEs) through gravitational lensing (GL) are...
High redshift galaxies in the ALHAMBRA survey . I. Selection method and number counts based on redshift PDFs
Context. Most observational results on the high redshift restframe UV-bright galaxies are based on samples pinpointed using the so-called dropout technique or...
High redshift galaxies in the ALHAMBRA survey. II. Strengthening the evidence of bright-end excess in UV luminosity functions at 2.5 ≤ z≤ 4.5 by PDF analysis
Context. Knowing the exact shape of the ultraviolet (UV) luminosity function (LF) of high-redshift galaxies is important to understand the star formation...
High resolution IR observations of the starburst ring in NGC 7552. One ring to rule them all?
Aims: Approximately 20% of all spiral galaxies display starburst activity in nuclear rings of a few hundred parsecs in diameter. It is our main aim to...
High spatial resolution mid-infrared spectroscopy of the starburst galaxies NGC 3256, II Zw 40 and Henize 2-10
Aims.In order to show the importance of high spatial resolution observations of extra-galactic sources when compared to observations obtained with larger...
High velocity clouds around nearby galaxies from THINGS
As a sub-set of activities within the THINGS (The HI Nearby Galaxy Survey) collaboration we have used the HI maps of the complete set of galaxies observed in...
