Whispers special session: Massive data processing and analysis in radioastronomy, Amsterdam, September 26, 2019
First announcement and call for oral contributions and posters, deadline:
Friday June 28th in the evening.
Datasets produced by the current and future generations of radio telescopes
are becoming extremely large, due to the increase in sensitivity,
instantaneous bandpass per pixel and number of pixels per receiver. This is
true for the (sub)millimeter domain where the main instruments (IRAM-30m,
NOEMA, ALMA, APEX, LMT, etc) now routinely process several tens of GHz with
spectral resolutions of the order of 100 kHz (implying the measurements of
about 500,000 frequencies simultaneously), as well as for the centimeter
domain (VLA, FAST, LOFAR) and the foreseen SKA that will again represent a
revolution in data rate. Data processing and analysis of these large
volumes require the development of innovative methods based on the most
recent advances in signal processing.
To get the best out of such powerful telescopes, and answer key questions
on a wide range of astrophysical topics (from the origin of stars and
planets, to cosmic dawn), requires to build bridges between the astronomy
community and the applied mathematics / signal processing communities. The
proposed one-day session during the Whispers (Workshop on Hyperspectral
Image and Signal Processing: Evolutions in Remote Sensing) workshop in
Amsterdam aims at presenting the challenges encountered by the
radio-astronomy community and the on-going activities to solve them. This
event will be organized in 3 to 4 sessions of four to five 20-minutes
contributed talks introduced by two invited presentations to set the field
Anna Scaife (Manchester, UK ): Radioastronomy challenges in cosmology and galaxy evolution studies
Susan Clark (Princeton, USA): Atomic and molecular line imaging as diagnostics for ISM and star formation
Posters will be presented during a flash session. The day will end with a
round table to define directions for future collaborations. This table will
be animated by Cyril Tasse (Obs. de Paris, France), Yves Wiaux
(Heriot-Watt, UK, TBC), and the SOC members.
The themes of the workshop include
* Single dish and interferometer data processing
* Filtering of artifacts and denoising
* Structure identification with or without velocity information
* Identification and quantification of temporal variations
* Data - model comparisons
The astrophysics focus is put on the topics benefiting from advanced
* The relationship between interstellar medium properties and star
formation, from the local universe to distant galaxies.
* Observational constraints on Cosmic dawn and the epoch of reionization .
Registration is mandatory, with a reduced fee (190 euros) for the one day
special session. The fee includes lunch and coffee breaks. Participants
are invited to register and submit either an abstract, an already published
paper, or an original paper for publication in IEEE.
* Submission deadline: 28 June 2019 (This is the actual deadline for this
special session. Please disregard the website deadline.)
* Final program: 15 July 2019.
* End of registration: 10 September 2019.
* Special session: 26 September 2019.
