GELATO
Supernova classifications made easy
Easy Supernova classifications for everyone and everywhere.
GELATO performs an automatic comparison of a given (input) spectrum with its database of well-studied SN spectra (templates), in order to find the templates that are most similar to the input one. After the comparison process the user is provided with the best matching templates and their characteristics (SN type, phase, etc), that objectively classify the input spectrum. To make it even easier, GELATO provides comparison plots of the input spectrum and templates.
GELATO has responsive UI which provides optimal user experience
on mobile devices too!
Please take into account that the classification results provide optional
comparison plots of spectra, and GELATO does its best to render the plots usable even for the
reduced screen sizes of smartphones. Nevertheless, you may find challenging viewing
spectra on a small screen, so please try and decide yourself.
Some mobile devices (in particular iOS based ones) by default do not allow direct user
access to the file system and consequently file uploads to web services through standard web browsers.
As GELATO requires you to upload your SN spectrum in order to classify it, it cannot
be used on these devices, unless additional third party applications are installed to
bypass the operating system's native behaviour.
GELATO templates
are hand-picked SN spectra of all SNe types,
spanning a wide range of characteristics and SN evolution phases. Only spectra of
very well studied SNe are chosen and visually examined one by one.
The templates database is
continuously growing with new additions, and these updates are immidiately
available to all GELATO users!
GELATO cares about your privacy!
The email address requested to sign you up is used only
to provide you access to GELATO and help you to reset your password if you
need it one day. Your email address will not be used for anything else, neither will it be shared
to third parties. According to the
Spanish personal data privacy law
(the TNG is located in Spain), you can, at any moment, request that GELATO
deletes your email address.
GELATO removes all your session data, including your
spectrum, at the exact moment when you sign out clicking any of the "Sign out" links available
throughout your session. If you do not sign out, your session stays active for 6 hours after your
last classification and you can resume using GELATO without signing in. GELATO does this to offer
you more flexibility. After 6 hours your session is closed and all related session data are
automatically removed by a specially designed routine procedure.
GELATO is developed
by Avet Harutyunyan and
Padova-Asiago Supernova Group
and is based on the algorithm descibed in Harutyunyan et al., 2008, A&A, 488, 383.
GELATO is hosted by the
Telescopio Nazionale Galileo.
GELATO is offered "as-is". No warranty of any kind is expressed or implied.
