ESA's Herschel Space Observatory was launched on 14 May 2009. After a short commissioning and performance verification period, the science demonstration observations started in September 2009. Herschel is now carrying out routine science observations.

The three instruments (SPIRE, PACS and HIFI) are working extremely well. The IAC is part of the SPIRE and PACS instrument consortia and has contributed flying hardware and software.

The first results of the many Herschel Key Projects were presented at the ESLAB 2010 symposium in ESTEC (May 2010) and have been published in July 2010 in a special issue of Astronomy and Astrophysics (Vol. 518):

The Herschel Multi-tiered Extragalactic Survey (HerMES, hermes.sussex.ac.uk/) is an astronomical project to study the evolution of galaxies in the distant Universe. HerMES is the largest project on ESA's Herschel Space Observatory. The project is carried out by a large team, made up primarily of people who built the SPIRE instrument on Herschel.

The first results of the HerMES survey were published in the special issue of Astronomy and Astrophysics. Some of these papers are in collaboration with the PACS Evolutionary Probe (PEP) extragalactic survey (http://www.mpe.mpg.de/ir/Research/PEP/).

    Constraints on the in situ and ex situ stellar masses in nearby galaxies obtained with artificial intelligence
    The hierarchical model of galaxy evolution suggests that mergers have a substantial impact on the intricate processes that drive stellar assembly within a galaxy. However, accurately measuring the contribution of accretion to a galaxy's total stellar mass and its balance with in situ star formation poses a persistent challenge, as it is neither directly observable nor easily inferred from observational properties. Using data from MaNGA, we present theory-motivated predictions for the fraction of stellar mass originating from mergers in a statistically significant sample of nearby galaxies

    Hydrogenated amorphous carbon grains as a carrier of unidentified IR bands in planetary nebulae
    It is well known that fullerenes – big, complex, and highly resistant carbon molecules with potential applications in nanotechnology – are mostly seen in planetary nebulae (PNe); old dying stars with progenitor masses similar to our Sun. Fullerenes, like C60 and C70, have been detected in PNe whose infrared (IR) spectra are dominated by broad unidentified IR (UIR) plateau emissions. The identification of the chemical species (structure and composition) responsible for such UIR emission widely present in the Universe is a mystery in astrochemistry; although they are believed to be carbon-rich

    The universal variability of the stellar initial mass function probed by the TIMER survey
    The universality of the stellar initial mass function (IMF) is one of the most widespread assumptions in modern Astronomy and yet, it might be flawed. While observations in the Milky Way generally support an IMF that is invariant with respect to the local conditions under which stars form, measurements of massive early-type galaxies systematically point towards a non-universal IMF. To bridge the gap between both sets of evidence, in this work we measured for the first time the low-mass end of the IMF from the integrated spectra of a Milky Way-like galaxy, NGC3351. We found that the slope of
