Assistive Tele-op: Leveraging Transformers to Collect Robotic Task Demonstrations

Kavli Affiliate: Kevin Parker | First 5 Authors: Henry M. Clever, Ankur Handa, Hammad Mazhar, Kevin Parker, Omer Shapira | Summary: Sharing autonomy between robots and human operators could facilitate data collection of robotic task demonstrations to continuously improve learned models. Yet, the means to communicate intent and reason about the future are disparate between […]

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

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

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

Kavli Affiliate: Dheeraj R. Pasham | 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 […]

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

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

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 […]
