First results on SiSeRO (Single electron Sensitive Read Out) devices — a new X-ray detector for scientific instrumentation

Posted by klaurent MIT

Kavli Affiliate: Marshall Bautz | First 5 Authors: Tanmoy Chattopadhyay, Sven Herrmann, Barry Burke, Kevan Donlon, Gregory Prigozhin | Summary: We present an evaluation of a novel on-chip charge detector, called the Single electron Sensitive Read Out (SiSeRO), for charge-coupled device (CCD) image sensor applications. It uses a p-MOSFET transistor at the output stage with […]

Probing the properties of superheavy dark matter annihilating or decaying into neutrinos with ultra-high energy neutrino experiments

Posted by klaurent Chicago

Kavli Affiliate: Angela V. Olinto | First 5 Authors: Claire Guépin, Roberto Aloisio, Luis A. Anchordoqui, Austin Cummings, John F. Krizmanic | Summary: The evidence for dark matter particles, $chi$, is compelling based on Galactic to cosmological scale observations. Thus far, the promising weakly interacting massive particle scenario have eluded detection, motivating alternative models of […]

Evidence for a Compact Object in the Aftermath of the Extra-Galactic Transient AT2018cow

Posted by klaurent MIT

Kavli Affiliate: Ronald Remillard | First 5 Authors: Dheeraj R. Pasham, Wynn C. G. Ho, William Alston, Ronald Remillard, Mason Ng | Summary: The brightest Fast Blue Optical Transients (FBOTs) are mysterious extragalactic explosions that may represent a new class of astrophysical phenomena. Their fast time to maximum brightness of less than a week and […]

Forward-modelling the Luminosity, Distance, and Size distributions of the Milky Way Satellites

Posted by Chicago

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Viraj Manwadkar, Andrey Kravtsov, , , | Summary: We use texttt{GRUMPY}, a simple regulator-type model for dwarf galaxy formation and evolution, to forward model dwarf galaxy satellite population of the Milky Way (MW) using the Caterpillar zoom-in simulation suite. We show that luminosity and distance distributions of […]

Detection of spatial clustering in the 1000 richest SDSS DR8 redMaPPer clusters with Nearest Neighbor distributions

Posted by klaurent Stanford

Kavli Affiliate: Tom Abel | First 5 Authors: Yunchong Wang, Arka Banerjee, Tom Abel, ., | Summary: Distances to the $k$-nearest-neighbor ($k$NN) data points from volume-filling query points are a sensitive probe of spatial clustering. Here we present the first application of $k$NN summary statistics to observational clustering measurement, using the 1000 richest redMaPPer clusters […]

The Pantheon+ Analysis: Forward-Modeling the Dust and Intrinsic Colour Distributions of Type Ia Supernovae, and Quantifying their Impact on Cosmological Inferences

Posted by Chicago

Kavli Affiliate: Richard Kessler | First 5 Authors: Brodie Popovic, Dillon Brout, Richard Kessler, Daniel Scolnic, | Summary: Recent studies have shown that the observed colour distributions of Type Ia SNe (SNIa) are well-described by a combination of distributions from dust and intrinsic colour. Here we present a new forward-modeling fitting method (Dust2Dust) to measure […]

Creating Multimodal Interactive Agents with Imitation and Self-Supervised Learning

Posted by klaurent Berkeley

Kavli Affiliate: Felix Fischer | First 5 Authors: DeepMind Interactive Agents Team, Josh Abramson, Arun Ahuja, Arthur Brussee, Federico Carnevale | Summary: A common vision from science fiction is that robots will one day inhabit our physical spaces, sense the world as we do, assist our physical labours, and communicate with us through natural language.
