General announcement
- Happy new year 2025
- 本年もよろしくお願いします。
- 2025年はO4b観測に向けた感度向上、O4b観測を計画
- O4 PEM paperをpublishしたいので、ご協力いただける方はご連絡ください。
- Author list 2024
- Thank you for your contribution
- Virgo ENV member have some plan to visit KAGRA about 1 month
- Jan., Feb. or Mar. one month
- Plan
- Noise hunting (PEM injection) toward the 10 Mpc would be first priority
- Power supply operation
- Magnetic injection
- Additional NN measurement
- Other
- O4a noise budget paper
- If you have a plan to write the paper using O4a data and PEM, please let me know.
- Start the investigation for the new subsystem, noise subtraction, under the SEO.
- Establish next year
