    I am on my way home to # Canada from # Vienna . Currently on a short layover in # Frankfurt . # Vienna was wonderful and the # TAUP2023 conference was amazing. Attached is a photo from the conference dinner, held in the city hall. It was a remarkable venue for dinner. https://chirp.cooleysekula.net/attachment/f52ae92bc0d5d74e96831fbf68c074b60f248309182c77f90483a8b32707ecd5/view

    The current age of # GravitationalWave astronomy is breathtaking. The next age will be mind blowing. Between # LISA and at least one large-scale ground-based # Laser # Interferometer , plus the # Pulsar Network and # Cosmic # Microwave # Background approaches, there will be coverage from the Planck scale/birth of the universe to the merging of # Sueprmassive # BlackHoles and even # Supernova explosions. # TAUP2023

    Had a great time presenting the # HALO Collaboration poster on a preliminary look at neutron multiplicity in "bursts" in our detector. A burst is a sequence of neutrons (3 or more) that lie within 3ms. Had great conversations with the people that stopped by the poster session today. Check out the poster: https:// indico.cern.ch/event/1199289/c ontributions/5445885/ https://chirp.cooleysekula.net/attachment/e9162da81a6467ce2dc81d7b9aaa07a6090af4dfd19690dd4eb0a43db96b8ed9/view

    I am really excited about the effort from experiments like # ANAIS and # COSINUS to definitely understand the "quenching factor" of sodium iodide crystals. NaI has appeared in many experiments, and increasingly in # darkmatter experiments. The QF relates energy in electrons (usually what you see in an experiment) to the energy of the original nuclear recoil. The QF is essential to proper interpretation of experiments using NaI.

    Lessons from the # TAUP conference: 1. The fundamental nature of the neutrino, as a fermion, is a crucial goal … and one that continues to prove challenging. 2. The cosmic microwave background has at least two big questions left, and they are hard: what is the polar structure of the light itself, and what can gravitational microlensing of that light tell us about large-scale structure of the more recent universe?

    From vicgrinberg@mastodon.social on Mastodon: Want to know what my research is about? Follow this thread đź§µ based on a 10min talk I've drawn for a meeting. The talk was aimed at non-specialist space science colleagues (not the general public!). The slides were built up step by step, but I'm omitting this here

    From mcnees@mastodon.social on Mastodon: Katherine Johnson passed away in 2020, at the age of 101. Editorial cartoonist Steve Breen’s lovely tribute perfectly captured Johnson’s contributions to the US space program.

    Getting ready to depart # Toronto for # Vienna ! Had a nice afternoon in the airport enjoying decaf coffee and chamomile tea while reading up on dark matter "freeze-in", one of the theoretical mechanisms by which a population of dark matter would be locked into the universe after the Big Bang. https://chirp.cooleysekula.net/attachment/bbaadd1004672e7040446dce9ff8f36a289f5fa7d83cdf9929ec634cc84541db/view

    From jodi on Mastodon: Before leaving Whitby, I hand to make one last stop at the @WhitbyMuseum to see the Zeplin-III experiment that operated in the @BoulbyLab many years ago.

    My companion on the journey to # Vienna today for the # TAUP conference (Topics in # Astroparticle and Underground # Physics ). I have been looking forward to reading this for weeks. I read when I travel, so my pace is very slow to work through books. https://chirp.cooleysekula.net/attachment/4d4cb89819101225aaa29896236a9912ea626f1b0b1e8fb0e55b511109ad0da3/view

    From hfalcke@mastodon.social on Mastodon: Congratulations to our Indian colleagues who achieved their first soft landing on the moon. Only very few countries have achieved that and particularly not in recent times, where we saw lots of crash landings. They are first on the South Pole. I remember how we were proposing a European lunar lander South Pole Mission 15 years ago and seeing soft landing experiments at EADS. Europe didn’t pull it through. India did. # Moon # Chandrayaan3 # Astrodon
