Back to Data Analysis

Introduction

The Transient Science Group focuses on the analysis of detection, spectra, and time variability of transient sources such as GRBs.

Current Coordinators:

• Alice Donini (Leader), INAF OAR, Italy, alice.donini@inaf.it
• Monica Seglar-Arroyo (Deputy), IFAE, Spain, mseglar@ifae.es

Past Coordinators:

• Armand Fiasson (Leader), LAPP, France, armand.fiasson@lapp.in2p3.fr

Mailing list and slack channels

Join our mailing list here!

We have several channel in the CTA North Slack Workspace:

• #lst1-alert-followup to discuss the received alerts or any interesting event

• #lst1-transient-analysis to discuss the analysis of the observed events

Main topics

• Gamma-Ray Bursts (GRBs)
• Gravitational Waves (GWs)
• Neutrino Observations

Proposals

2023:

• TRAN01: Follow-up of gravitational wave events
  
• TRAN02: Gamma-ray burst observations
  
• TRAN03: Tick-Tock: Monitoring of an inspiraling binary SMBH
  

Papers in progress:

• GRB221009A - Link to analysis page
