Observation of Seven Astrophysical Tau Neutrino Candidates with IceCube
We report on a measurement of astrophysical tau neutrinos with 9.7 years of IceCube data. Using convolutional neural networks trained on images derived from simulated events, seven candidate $ν_τ$ events were found with visible energies ranging from roughly 20 TeV to 1 PeV and a median expected parent $ν_τ$ energy of about 200 TeV. Considering backgrounds from astrophysical and atmospheric neutrinos, and muons from $π^\pm/K^\pm$ decays in atmospheric air showers, we obtain a total estimate…

GROS: A General Robust Aggregation Strategy
A new, very general, robust procedure for combining estimators in metric spaces is introduced GROS. The method is reminiscent of the well-known median of means, as described in \cite{devroye2016sub}. Initially, the sample is divided into $K$ groups. Subsequently, an estimator is computed for each group. Finally, these $K$ estimators are combined using a robust procedure. We prove that this estimator is sub-Gaussian and we get its break-down point, in the sense of Donoho. The robust procedure in…

The Squared Kemeny Rule for Averaging Rankings
For the problem of aggregating several rankings into one ranking, Kemeny (1959) proposed two methods: the median rule which selects the ranking with the smallest total swap distance to the input rankings, and the mean rule which minimizes the squared swap distances to the input rankings. The median rule has been extensively studied since and is now known simply as Kemeny's rule. It exhibits majoritarian properties, so for example if more than half of the input rankings are the same, then the ou…

Fast Approximations and Coresets for (k, l)-Median under Dynamic Time Warping
We present algorithms for the computation of $\varepsilon$-coresets for $k$-median clustering of point sequences in $\mathbb{R}^d$ under the $p$-dynamic time warping (DTW) distance. Coresets under DTW have not been investigated before, and the analysis is not directly accessible to existing methods as DTW is not a metric. The three main ingredients that allow our construction of coresets are the adaptation of the $\varepsilon$-coreset framework of sensitivity sampling, bounds on the VC dimensio…

The size and shape dependence of the bispectrum of the SDSS DR17 main galaxy sample
We have measured the spherically averaged bispectrum of the SDSS DR17 main galaxy sample, considering a volume-limited $[273\, \rm Mpc]^3$ data cube with mean galaxy number density $1.76 \times 10^{-3} \, {\rm Mpc}^{-3}$ and median redshift $0.093$. Our analysis considers $\sim 1.37 \times 10^{8}$ triangles, for which we have measured the binned bispectrum and analyzed its dependence on the size and shape of the triangle. It spans wavenumbers $k_1=(0.082-0.472)\,{\rm Mpc}^{-1}$ for equilateral …

Molecular gas scaling relations for local star forming galaxies in the low-$M_*$ regime
We derive molecular gas fractions ($f_\mathrm{mol}=M_\mathrm{mol}/M_*$) and depletion times ($τ_\mathrm{mol}= M_\mathrm{mol}/\mathrm{SFR} $) for 353 galaxies representative of the local star-forming population with $10^{8.5}\,M_\odot < M_* < 10^{10.5}\,M_\odot$ drawn from the ALLSMOG and xCOLDGASS surveys of CO(2-1) and CO(1-0) line emission. By adding constraints from low-mass galaxies and upper limits for CO non-detections, we find the median molecular gas fraction of the local star-forming …
