“VEGAS:
VST Early-type GAlaxy Survey
VEGAS is a deep multi-band (u’g’r’i’) imaging survey, carried out with the ESO VLT Survey Telescope (VST). VST is a 2.6-m wide-field optical survey telescope, located at ESO Paranal Observatoryy“
Science
Exploring the low surface brightness (LSB) universe is one of the most challenging tasks in the era of the deep imaging and spectroscopic surveys.
It is however a crucial ingredient to map the mass assembly of galaxies at all scales and all environments and thus constrain their formation within the Lambda-Cold Dark Matter paradigm.
In this framework, clusters of galaxies are expected to grow over time by accreting smaller groups. During the infall process, the material stripped from the galaxy outskirts builds up the stellar halos and the intracluster light (ICL; see e.g. Contini et al. 2014; Cui et al. 2014; Pillepich et al. 2018). These are diffuse and very faint (μg > 26 mag/arcsec2) components made of stars stripped from satellite galaxies, also in the form of streams and tidal tails, with multiple stellar population and complex kinematics, which are still growing at the present epoch.
VEGAS science goals
to map the light distribution and colors out to 8-10 Re and down to the faint surface brightness levels of μg ≃ 31 mag/arcsec2, μr ≃ 28 mag/arcsec2; μi ≃ 27 mag/arcsec2
to study of the galaxy structure and its faint stellar halo, including the diffuse light component, inner substructures as signatures of recent cannibalism events, inner disks and bars
detection of the external low-surface brightness structures in galaxies, like tidal tails, stellar streams and shells and study the connection with environment
for galaxies in the local universe (D<50 Mpc), to census and study the globular clusters and galaxy satellites in the outermost regions of the host galaxy
the full will provide essential statistical constraints on theoretical models and enable discrimination among competing galaxy formation theories. Ongoing projects
planned works in 2019 – 2021

Data Reduction
“First VEGAS observations (2014-2016) have been processed with the VST-tube pipeline specialized for the VST-OmegaCam observations
(see Grado et al. 2012; Capaccioli et al. 2015)
Since 2018, the VEGAS data are reduced with the AstroWise data-reduction pipeline
Dr. Marilena Spavone, at INAF-Astronomical Observatory of Capodimonte is leading and coordinating this task.
Both pipelines perform the standard pre-reduction steps, gain harmonisation of the 32 CCDs, illumination correction and, for the i band, defringing. Relative and absolute astrometric and photometric calibrations are applied before creating the final co-added image mosaics.
In addition, there are two tasks to perform the sky subtraction, depending on the adopted observing strategy :
– fitting of the background with a surface, typically a 2D polynomial, to the pixel values of the mosaic;
– for images acquired with the step-dither observing strategy, an average sky frame is obtained from exposures taken as close as possible, in space and time, to the scientific ones.
Observing strategies
Step-dither:
the brightest and most extended galaxies (with mB < 10 mag and a major axis diameter larger than 5 arcmin), a good background estimate is achieved by adopting the step-dither observing sequence (see Iodice et al. 2016, 2017, Spavone et al. 2017, Iodice et al. 2019).
It consists of a cycle of short exposures, 5 x 150 sec on the target (science frame) and 5 x 150 sec on the sky frame.
Standard:
For less extended objects, the sky background can be estimated on the science frame, by using a polynomial surface fit over the entire frame (see Capaccioli et al. 2015). In this case, the adopted observing strategy is the standard diagonal dithers to cover the CCD gaps.”
The Fornax Deep Survey (FDS) with VST
“DS is a new, multi-band imaging survey of the Fornax cluster of galaxies FDS is a joint project based on the GTO survey FOrnax Cluster Ultra deep Survey (FOCUS, P.I. R. Peletier) and VEGAS (P.I. E. Iodice)
FDS aims to cover the whole Fornax cluster out to the virial radius (~0.7 Mpc), with an area of about 26 square degrees around the central galaxy NGC1399 (top panel), and the region where NGC1316 is located, on the SW (left panel)”

Caught in a spiral
The image shows a pair of overlapping spiral galaxies, NGC 3314a and b, in the top left, caught in a majestic cosmic dance — captured by ESO’s VLT Survey Telescope (VST). But don’t let the perspective fool you! They are, in fact, not interacting at all. The two galaxies, located between 117 and 140 million light-years away in the constellation of Hydra, are actually physically unrelated and only appear to overlap when viewed from Earth. This unique alignment gives astronomers the opportunity to measure many properties of the galaxies, such as how dust absorbs starlight, and hence gain insight into their composition and evolution. There is another hidden secret in this picture if you look closely at the lower right region: beyond this stunning cosmic dance you will find a faint yellowish smudge, the signature of an ultra-diffuse galaxy (UDG). UDGs are objects as large as the Milky Way but with 100 – 1000 times fewer stars. These galaxies are extremely faint and lack star-forming gas, which makes them appear almost like a smudge in the night sky. This UDG, named UDG 32, is one of the faintest and most spread out galaxies in the Hydra I cluster. This image was taken as part of a much larger project, the VST Early-type Galaxy Survey (VEGAS), whose goal is to investigate very faint structures in galaxy clusters — large groups of galaxies held together by gravity. The study, led by Enrichetta Iodice from the Istituto Nazionale di Astrofisica in Italy, suggests that UDG 32 may have formed out of the filaments stemming from NGC 3314a, but more observations are needed to confirm this.

Dates
Registration
Motivation:
VEGAS will end in 2022, in P108 ESO period. The latest observing runs will be executed in P109 as carry over from P107.
This meeting aims at making an overview of the project, providing the main achievements and results.
Main goals of the meeting:
How VEGAS contributed to the panorama of the (ongoing) deep imaging surveys?
Which is the expertise that we have collected in ~10years of the project?
How well performed the VST as optical survey telescope compared to the others of its class?
What about the cross-collaborations (i.e. FDS) and follow-ups using other facilities (e.g., FORS2, MUSE, MeerKAT)?
Given that, how we can contribute to the upcoming science with the upcoming facilities for large surveys (e.g. EUCLID, LSST)?
