    Halo-Disk vs. Shrinking Scenarios
    We discuss the possibility that the extended structures, lacking young stars, routinely found in dwarf irregular galaxies (dIrr) are a consequence of a...

    Harassment origin for kinematic substructures in dwarf elliptical galaxies?
    We have run high resolution N-body models simulating the encounter of a dwarf galaxy with a bright elliptical galaxy. The dwarf absorbs orbital angular momentum...

    HARMONI view of the host galaxies of active galactic nuclei around cosmic noon. Resolved stellar morpho-kinematics and the M<SUB>BH</SUB> − σ<SUB>⋆</SUB> relation
    Context. The formation and evolution of galaxies appear linked to the growth of supermassive black holes, as evidenced by empirical scaling relations in nearby...

    Have we seen all the galaxies that comprise the cosmic infrared background at 250 μm ≤ λ ≤ 500 μm?
    The cosmic infrared background (CIB) provides a fundamental observational constraint on the star formation history of galaxies over cosmic history. We estimate...

    Heavy-element yields and abundances of asymptotic giant branch models with a Small Magellanic Cloud metallicity
    We present new theoretical stellar yields and surface abundances for asymptotic giant branch (AGB) models with a metallicity appropriate for stars in the Small...

    HELP project - a dreamed-of multiwavelength dataset for SED fitting: The influence of used models for the main physical properties of galaxies
    The Herschel Extragalactic Legacy Project (HELP) focuses to publish an astronomical multiwavelength catalogue of millions of objects over 1300 deg 2 of the...

    HELP: a catalogue of 170 million objects, selected at 0.36-4.5 μm, from 1270 deg<SUP>2</SUP> of prime extragalactic fields
    We present an optical to near-infrared (NIR) selected astronomical catalogue covering 1270 deg 2. This is the first attempt to systematically combine data from...

    HerMES: a search for high-redshift dusty galaxies in the HerMES Large Mode Survey - catalogue, number counts and early results
    Selecting sources with rising flux densities towards longer wavelengths from Herschel/Spectral and Photometric Imaging Receiver (SPIRE) maps is an efficient way...

    HerMES: A Statistical Measurement of the Redshift Distribution of Herschel-SPIRE Sources Using the Cross-correlation Technique
    The wide-area imaging surveys with the Herschel Space Observatory at submillimeter (sub-mm) wavelengths have now resulted in catalogs of the order of one...
