157. Anomaly Detection in Astronomical Data using Machine Learning

Dr Michelle Lochner (University of the Western Cape/ South African Radio Astronomy Observatory)

14/10/2022, 11:00

Invited Talk

The next generation of telescopes such as the SKA and the Vera C. Rubin Observatory will produce enormous data sets, far too large for traditional analysis techniques. Machine learning has proven invaluable in handling large data volumes and automating many tasks traditionally done by human scientists. In this talk, I will discuss how machine learning for anomaly detection can help automate...

123. Multi-wavelength data analysis with the threeML framework

Nicola Omodei (Stanford University)

14/10/2022, 11:30

Contributed Talk

With an increasing number of observatories making their data publicly available, we have truly reached the era of multi-wavelength astronomy. Combining gamma-ray data from multiple instruments as well as with measurements at other wavelengths is needed to unlock the data's full potential. However, lack of standardization as well as unique challenges of each instrument can make combining data...

141. The Fermi Light Curve Repository

Dan Kocevski

14/10/2022, 11:45

Contributed Talk

The Fermi Large Area Telescope Light Curve Repository (LCR) provides publication quality light curves on timescales of days, weeks, and months for over 1500 sources deemed variable in the 4FGL-DR2 catalog. The repository consists of light curves generated using a full likelihood analysis of the source and surrounding region, providing calibrated flux and photon index measurements for each time...

156. Identifying multiwavelength counterparts to astrophysical neutrino events

Dr Marcos Santander (University of Alabama)

14/10/2022, 12:00

Contributed Talk

At production, high-energy neutrinos originating in astrophysical sources should be accompanied by gamma-rays. Depending on the properties of the emission environment and the distance of the source to Earth these gamma rays may be observed directly, or through the detection of lower energy photons that result from the interaction of these gamma rays with intervening radiation fields. We here...

125. General Coordinates Network (GCN): NASA’s Next Generation Time-Domain and Multimessenger Astronomy Alert System

Dr Judith Racusin (NASA/GSFC)

14/10/2022, 12:15

Contributed Talk

The Gamma-ray Coordinates Network (GCN) is a public collaboration platform run by NASA for the astronomy research community to share alerts and rapid communications about high-energy, multimessenger, and transient phenomena. Over the past 30 years, GCN has helped enable many seminal advances by disseminating observations, quantitative near-term predictions, requests for follow-up observations,...

124. Astro-COLIBRI

Patrick Reichherzer

14/10/2022, 12:30

Contributed Talk

Astro-COLIBRI is a novel platform that evaluates alerts of transient observations in real time, filters them by user-specified criteria, and puts them into their multiwavelength and multimessenger context. Through fast generation of an overview of persistent sources, as well as transient events in the relevant phase space, Astro-COLIBRI contributes to an enhanced discovery potential of both...

54. easyFermi: a graphical interface for performing Fermi-LAT data analyses

Raniere Menezes (Universidade de São Paulo)

14/10/2022, 12:45

Contributed Talk

Since its launch in 2008, the Fermi Large Area Telescope (LAT) allowed us to investigate the extremely energetic side of the Universe with unprecedented sensitivity and resolution. The tools available for analyzing Fermi-LAT data are the Fermitools and Fermipy, both of which can be scripted in Python and run via command lines in a terminal or in web-based interactive computing platforms. In...
