Giovanni Cresci

The priettiest astronomer ever

I work as staff researcher at Osservatorio Astrofisico di Arcetri in Firenze, Italy, which is part of INAF, the Italian National Institute for Astrophysical Research.

My research interests are mainly in the field of Galaxy Evolution with an observational approach, mostly focusing on the evolution of ISM and chemical enrichment with cosmic time and on the effects and properties of AGN feedback

I'm also involved in several new instrumentation projects, such as NIRSpec on JWST, MOONS at VLT, ERIS at VLT, HIRES for ELT

AGN Feedback

Outflows and feedback in active galaxies with MUSE and SINFONI Integral Field Spectroscopy. My group provided the first evidences of Positive and Negative feedback on AGN host galaxies

MAGNUM (Measuring Active Galactic Nuclei Under MUSE Microscope) is a MUSE@VLT integral field survey of 10 among the closest and best studied Active Galaxies

SUPER (SINFONI Survey for Unveiling the Physics and the Effect of Radiative feedback) is a SINFONI Large Program to carry out the first statistically-sound investigation of ionised outflows in AGN host galaxies at the peak epoch of AGN and galaxy assembly, z~2. It consists of 280 hours of SINFONI observations in LGS Seeing Enhancer mode to reach a spatial resolution of 1 kpc at z~2.

Chemical Evolution of galaxies

Metallicity evolution of the Universe using scaling relations as the Mass-Metallicity and the Fundamental Metallicity Relation

KLEVER (Kmos LEnsed Velocity and Emission line Review) is an ESO Large Programme exploiting the multi-IFU near-IR spectrograph KMOS at the Very Large Telescope. The goal is to obtain spatially resolved spectroscopy of a sample of about 200 galaxies in the redshift range z~1-2.5, in all three primary near-IR bands (J, H, K) so to map all of the primary optical nebular lines redshifted into the near-IR bands ([OII], [NeIII], He II, Hβ, [OIII], Hα, [NII], [SII], [SIII]). The combination of these multiple lines will enable us to investigate in detail the physical properties of the ISM in galaxies (excitation mechanism, chemical enrichment, ionization parameter, density, etc...) with an accuracy that has not been possible in previous large surveys.

AMAZE (Assessing the Mass Aboundance redshift-Z Evolution) and LSD,(Lyman-break galaxies Stellar populations and Dynamics): two italian projects aimed at studying spatially resolved dynamical an chemical evolution at redshift z>3, using integral field spectroscopy with SINFONI@VLT, multi object observation with LUCIFER@LBT, and XSHOOTER@VLT

Other observational projects

Star Formation in local Dwarf Galaxies, Integral Field Spectroscopy with MUSE and SINFONI at the VLT of local star forming Dwarf Galaxies, a unique test bench to study in detail the physical mechanisms that drive star formation and galaxy evolution in nearly pristine environments, resembling those in high-z galaxies

VANDELS, a deep VIMOS survey of the CANDELS UDS and CDFS fields, with ultradeep exposures up to 80 hours.

SINS/ZCSINS high redshift galaxy Spectroscopic Imaging survey in the Near-Ir, to study spatially resolved gas dynamics and ISM properties at z~2.

SWAN (Survey of Wide Area with NACO), an AO assisted imaging survey in the near-IR (Ph.D. Thesis: "Galaxy Morphology and Star Formation with Adaptive Optics")

KAOSS (K-band Arcetri Obscured Supernova Search), the first IR search for dust extincted Supernovae

Instrumental projects

Part of the GTO survey for the NIRSpec spectrograph on board of JWST, and collaboration with the ESA team to the characterization in the lab of its performances

Member of the Science Working Group for HIRES, High Resolution Spectrograph for ELT

Member of the ERIS (the next generation IR IFU and AO camera for the VLT) science team

Part of the MOONS (the multi-object NIR spectrometer for the VLT) development team in Arcetri and part of MOONS science working group

Coordinator of the “Physical parameter estimate from spectra” section of the “Galaxy and AGN” science working group for the Euclid satellite

Herschel Far-IR satellite PACS Instrument Control Center scientist for Italy (2012-2013)

Collaboration to the construction and commissioning and science verification of the multi-object near-IR spectrometer LUCI for the LBT, in collaboration with the LUCI team at MPE

Participation to the commissioning and science verification of the near-IR, AO assisted camera PISCES at LBT, in collaboration with INAF and LBT Observatory
