    Fun fact: I bought this cup in Geneva, Switzerland in the summer of 1998 when I spent the summer working at CERN before starting graduate school. I needed a reusable coffee cup since I was drinking a lot of CERN coffee. I have kept it ever since. https://twitter.com/drsekula/status/1405881677986123777/photo/1 https://chirp.cooleysekula.net/attachment/72263

    After a two week break, it was great to be refreshed and back at SMU to start summer research with one of the 4 students I will be working with this summer. Looking forward to ramping up work with the others and getting into a regular work rhythm again.

      Annual modulation results from three-year exposure of ANAIS-112
      from arXiv.org
      ANAIS (Annual modulation with NaI Scintillators) is a dark matter direct detection experiment consisting of 112.5 kg of NaI(Tl) detectors in operation at the Canfranc Underground Laboratory (LSC), in Spain, since August 2017. ANAIS' goal is to confirm or refute in a model independent way the DAMA/LIBRA positive result: an annual modulation in the low-energy detection rate having all the features expected for the signal induced by dark matter particles in a standard galactic halo. This modulation, observed for about 20 years, is in strong tension with the negative results of other very sensitive experiments, but a model-independent comparison is still lacking. By using the same target material, NaI(Tl), such comparison is more direct and almost independent on dark matter particle and halo models. Here, we present the annual modulation analysis corresponding to three years of ANAIS data (for an effective exposure of 313.95 kg$\times$y), applying a blind procedure which updates that developed for the 1.5 years analysis, and later applied to 2 years. The analysis also improves the background modelling in the fitting of the region of interest rates. We obtain for the best fit in the [1-6] keV ([2-6] keV) energy region a modulation amplitude of -0.0034$\pm$0.0042 cpd/kg/keV (0.0003$\pm$0.0037 cpd/kg/keV), supporting the absence of modulation in our data, and incompatible with DAMA/LIBRA result at 3.3 (2.6) $Οƒ$, for a sensitivity of 2.5 (2.7) $Οƒ$. Moreover, we include two complementary analyses: a phase-free annual modulation search and the exploration of the possible presence of a periodic signal at other frequencies. Finally, we carry out several consistency checks of our result, and we update the ANAIS-112 projected sensitivity for the scheduled 5 years of operation.

    I was so happy that @profcooley and I could welcome a few current or future graduate students to our home for a cookout. It was great to catch up with people in person and to just be able to be people again.

    The other troopers of this season are the potato plants that sprouted from a single half of one potato I planted a few weeks ago. This thing is growing fast and I am optimistic about a good crop of potatoes this time. https://www.instagram.com/accounts/login/
