Using white dwarf lensing to resolve accretion flows
Sophie L. Newman, Matthew J. Middleton, Adam McMaster
Microlensing is one of the most powerful tools for probing the nature of dark halo objects and the sources they lens. As our nearest massive galaxy, M31 provides a rich source popu…
Floating Forests: Quantitative Validation of Citizen Science Data Generated From Consensus Classifications
Isaac S. Rosenthal, Jarrett E. K. Byrnes, Kyle C. Cavanaugh +10
Large-scale research endeavors can be hindered by logistical constraints limiting the amount of available data. For example, global ecological questions require a global dataset, a…
Planet Four: Probing Springtime Winds on Mars by Mapping the Southern Polar CO Jet Deposits
K. -Michael Aye, Megan E. Schwamb, Ganna Portyankina +11
The springtime sublimation process of Mars' southern seasonal polar CO ice cap features dark fan-shaped deposits appearing on the top of the thawing ice sheet. The fan material…
A transient search using combined human and machine classifications
Darryl E. Wright, Chris J. Lintott, Stephen J. Smartt +22
Large modern surveys require efficient review of data in order to find transient sources such as supernovae, and to distinguish such sources from artefacts and noise. Much effort h…
Planet Four: Terrains - Discovery of Araneiforms Outside of the South Polar Layered Deposits
Megan E. Schwamb, Klaus-Michael Aye, Ganna Portyankina +7
We present the results of a systematic mapping of seasonally sculpted terrains on the South Polar region of Mars with the Planet Four: Terrains (P4T) online citizen science project…
Survey of Gravitationally-lensed Objects in HSC Imaging (SuGOHI). VI. Crowdsourced lens finding with Space Warps
Alessandro Sonnenfeld, Aprajita Verma, Anupreeta More +19
Strong lenses are extremely useful probes of the distribution of matter on galaxy and cluster scales at cosmological distances, but are rare and difficult to find. The number of cu…
Self-lensing binaries in globular clusters -- predictions for ELT
Grzegorz Wiktorowicz, Matthew Middleton, Mirek Giersz +4
Self-lensing (SL) represents a powerful technique for detecting compact objects in binary systems through gravitational microlensing effects, when a compact companion transits in f…
The K2-138 System: A Near-Resonant Chain of Five Sub-Neptune Planets Discovered by Citizen Scientists
Jessie L. Christiansen, Ian J. M. Crossfield, Geert Barentsen +25
K2-138 is a moderately bright (V = 12.2, K = 10.3) main sequence K-star observed in Campaign 12 of the NASA K2 mission. It hosts five small (1.6-3.3R_Earth) transiting planets in a…
VeSPA: The SuperWASP Variable Star Photometry Archive
Adam McMaster, Andrew J. Norton, Hugh J. Dickinson +2
We present the first results from the SuperWASP Variable Stars (SVS) citizen science project. The photometry archive of the Wide Angle Search for Planets has previously been search…
Planet Hunters TESS II: Findings from the first two years of TESS
Nora L. Eisner, Oscar Barragán, Chris Lintott +23
We present the results from the first two years of the Planet Hunters TESS citizen science project, which identifies planet candidates in the TESS data by engaging members of the g…
SuperWASP Variable Stars: Classifying Light Curves Using Citizen Science
Heidi B. Thiemann, Andrew J. Norton, Hugh J. Dickinson +2
We present the first analysis of results from the SuperWASP Variable Stars Zooniverse project, which is aiming to classify 1.6 million phase-folded light curves of candidate stella…
