Fast interactive web-based data visualizer of panoramic spectroscopic
  surveys
  Panoramic IFU spectroscopy is a core tool of modern observational astronomy
and is especially important for galaxy physics. Many massive IFU surveys, such
as SDSS MaNGA (10k targets), SAMI (3k targets), Califa (600 objects), Atlas3D
(260 objects) have recently been released and made publicly available to the
broad astronomical community. The complexity and massiveness of the derived
data products from spectral cubes makes visualization of the entire dataset
challenging, but nevertheless very important and crucial for scientific output.
Based on our past experience with visualization of spectral and imaging data
built in the frame of the VOxAstro Initiative projects, we are now developing
online web service for interactive visualizing spectroscopic IFU datasets
(ifu.voxastro.org). Our service will provide a convenient access and
visualization tool for spectral cubes from publicly available surveys (MaNGA,
SAMI, Califa, Atlas3D) and results of their modeling, as well as maps of
parameters derived from cubes, implementing the connected views concept. Here
we describe the core components and functionality of the service, including
REST API implementation on top of the Django+Postgres backend as well as a fast
and responsive user interface built using the modern Vue.js-based framework
Quasar.
