  5. Are gigaparsec structures like the "Giant Arc" breaking the standard model of #cosmology?

    No. We find similar patterns to be extremely common in a ΛCDM #universe, and we also show that the claimed overdensities are algorithmic artefacts.

    What's more, these shapes detected in extremely sparse samples of galaxies are just as easily found in random point patterrns, suggesting they're spurious and don't reflect any underlying structures.

  9. Nyt jännään, tiedottaako yliopisto asiasta julkisesti. Uutisoidaanko tätä? Oikeastaan toivon että ei. Päätös oli oikea, mutta tyylipisteitä saa tässä vaiheessa enää lähinnä vaikenemalla.

    Sisäisen Flamma-tiedotteen kommenteissa on riehunut (vain) kaksi trollia, ilmeisesti ihan oikeilla toimihenkilönimillään. (Ehkä toinen jo tajusi trollaavansa ja ettei oikeastaan tarkoittanut trollata?) Viestintätyyppien vastaukset ovat hyviä ja osoittavat ammattitaitoa. Tämä ilahduttaa.

  12. CW: sciencebrag

    Our paper about the role of little weird objects called 't Hooft-Polyakov monopoles during early universe phase transitions was published: link.springer.com/article/10.1

    Normally when you do Monte Carlo simulations of quantum field theories near phase transitions or in strongly coupled regimes, you get something rather different from the perturbative pen-and-paper-style calculation. But here, we found that the density of monopoles tracks the semiclassical result in this theory throughout the transition. Why, we don't really know.

    The picture (by Riikka Seppä) shows a snapshot of a 'cooled' simulation configuration with the monopoles in red and blue.

  20. @kaisa_karki @aydinonat Everybody talks about Mastodon, but I personally don't know anybody from #HelsinkiUni who uses it. Maybe somebody could write a short "Mastodon howto for academics". It took me seriously too much time to figure things out (and I still don't know many things, e.g. how to automatically crosspost #science or university-related blog posts from my #Drupal site to Mastodon).

  22. I'm David, a queer Finnish physicist originally from Scotland. I write on here in a personal capacity.

    I use big computers to simulate the very early universe.

    I also want to become a better teacher. For example, I want to understand what leads people from minoritised groups to abandon studies in physics.

    I help out with the local LGBTQ+ community, such as our LGBTQ+ STEM day events.
