While we are all waiting for T CrB to go Kaboom!, another long awaited event to chase is the next kilonova caused by a nearby binary neutron star (BNS) merger.
If you haven’t already joined the “Kilonova Catcher” (KNC) project, you might want to visit the next webinar and meeting:
Forwared from email:
Reminder regarding tomorrow’s webinar & meeting!
Andrew will be discussing classification with gravitational wave interferometers and the NSBH detection with S250206dm. We will also be discussing the new alert system for KNC.
Meeting Details:
Date: February 25, 2025
Time: 1900h UTC

Guest Speaker:
We’re excited to welcome Shar Daniels, a 3rd-year Astrophysics PhD student, who will be presenting:“Discovering Fast Optical Transients with Continuous Readout-Mode Imaging”
This talk will explore how continuous readout-mode imaging enables the detection of millisecond-duration optical transients – an emerging frontier in transient astrophysics!
This event is just our webinar, so we hope you’ll take the opportunity to join, ask questions, and learn more about cutting-edge research in fast transients.
See you there!

The next telecon (monthly meeting) is tomorrow!
Date: Tuesday, March 25th
Time: 1300h CDT/ 1400h EST / 1900 FR / 1800h UTC
Zoom Link: https://umn.zoom.us/j/8068498577Agenda:
1. Review of activities from the last month. How do you all feel about the alert system?
2. Update on the pre-processing manual.
3. Update on KNC Utilities (FORGE, use of KNC website for images)
4. Update on social media posts.
5. Update on monthly photo challenge: Deep Sky Objects. Currently, no one has submitted any NEW images. If these are not topics you are interested in, please let me know.
6. Update on topic requests. This form has had a few submissions. Thank you!
7. A short presentation by KNC member, Thierry Midavaine, on a topic of interest; a new technology from a company called Prophesee that could be applied to CMOS arrays where you can use machine learning to analyze the rise and fade of each pixel in an image.Regards,

Guest Speaker:
We’re excited to welcome Dr. Marion Pillas, a postdoctoral fellow at Liege University in Belgium. Dr. Pillas is also the chair for GRANDMA’s GRB Working Group and has written the GRB observing strategy for the collaboration.She will be presenting on her research and on her paper:
“Limits on the Ejecta Mass During the Search for Kilonovae Associated with Neutron Star-Black Hole Mergers: A case study of S230518h, GW230529, S230627c and the Low-Significance Candidate S240422ed”
This paper focuses on how neutron star–black hole (NSBH) mergers are expected to produce kilonovae (KNe), but none have been confirmed despite extensive follow-up of four NSBH candidates detected via gravitational waves during O4 (May 2023 – July 2024). This study evaluates why no KN was detected by analyzing multi-messenger observations and the observational coverage from over 50 instruments. Simulations show that most NSBH KNe peak around one day post-merger in g, r, i bands – often outside follow-up coverage. For some candidates, faint KN luminosity, large distances, or poor sky localization significantly limited detectability, and in one case (S240422ed), the lack of a KN supports a non-astrophysical origin.
This is a GRANDMA/KNC paper led by Dr. Pillas and Dr. Antier. It can be found on the KNC forge, here.
This event is just our webinar, so we hope you’ll take the opportunity to join, ask questions, and learn more about cutting-edge research in fast transients and the science community!
