The TASSIE Program. II: Three Close-In Companions Orbiting Sun-Like Stars
T. Plunkett, E. Thygesen, A. A. Cole +16
We present three southern transiting giant planet candidates alerted by the Transiting Exoplanet Survey Satellite (TESS) mission and investigated at the University of Tasmania Gree…
Euclid Quick Data Release (Q2) -- The Euclid Galactic Bulge Survey
J. -P. Beaulieu, E. Bachelet, M. Gilles +173
The Euclid Quick Data Release Q2 provides an unprecedented deep, wide-field, high-angular-resolution view of the inner Galactic bulge through the Euclid Galactic Bulge Survey (EGBS…
A Multiwavelength Assessment Disfavoring the X-ray Binary Origin of He III Regions in Metal-Poor Star-Forming Dwarf Galaxies
Ivan Altunin, Christopher Ellis, Richard M. Plotkin +9
Recent observations of metal-poor, star-forming dwarf galaxies reveal He III regions, traced by nebular He II 4686 emission that require a strong source of extreme-ultraviolet (EUV…
Historic microlensing events in the euclid Galactic Bulge Survey
V. Bozza, L. Salmeri, P. Rota +47
Microlensing campaigns have a long history of observations covering the Galactic bulge, where thousands of detections have been obtained, including many exoplanetary systems. The E…
The K2 and TESS Synergy III: search and rescue of the lost ephemeris for K2's first planet
Erica Thygesen, Joseph E. Rodriguez, Zoë L. De Beurs +13
K2-2 b/HIP 116454 b, the first exoplanet discovery by K2 during its Two-Wheeled Concept Engineering Test, is a sub-Neptune (2.5 0.1 , 9.7 1.2 ) orbi…
Characterization of K2-167 b and CALM, a new stellar activity mitigation method
Zoë L. de Beurs, Andrew Vanderburg, Erica Thygesen +13
We report precise radial velocity (RV) observations of HD 212657 (= K2-167), a star shown by K2 to host a transiting sub-Neptune-sized planet in a 10 day orbit. Using Transiting Ex…
Multiwavelength Scrutiny of X-ray Sources in Dwarf Galaxies: ULXs versus AGN
Erica Thygesen, Richard M. Plotkin, Roberto Soria +10
Owing to their quiet evolutionary histories, nearby dwarf galaxies (stellar masses ) have the potential to teach us about the mechanism(s) t…
The K2 & TESS Synergy II: Revisiting 26 systems in the TESS Primary Mission
Erica Thygesen, Jessica A. Ranshaw, Joseph E. Rodriguez +16
The legacy of NASA's K2 mission has provided hundreds of transiting exoplanets that can be revisited by new and future facilities for further characterization, with a particular fo…
Globular Cluster Ultraluminous X-ray Sources in the Furthest Early-Type Galaxies
E. Thygesen, Y. Sun, J. Huang +5
Ultraluminous X-ray Sources (ULXs) in globular clusters are low mass X-ray binaries that achieve high X-ray luminosities through a currently uncertain accretion mechanism. Using ar…
Another Shipment of Six Short-Period Giant Planets from TESS
Joseph E. Rodriguez, Samuel N. Quinn, Andrew Vanderburg +119
We present the discovery and characterization of six short-period, transiting giant planets from NASA's Transiting Exoplanet Survey Satellite (TESS) -- TOI-1811 (TIC 376524552), TO…
Ultraluminous X-ray Sources in Seven Edge-On Spiral Galaxies
Kristen C. Dage, Noah Vowell, Erica Thygesen +8
We investigate a sample of seven edge-on spiral galaxies using Chandra observations. Edge-on spiral galaxies allow us to clearly separate source associated with their star-forming…
Three Ultraluminous X-ray Sources Hosted by Globular Clusters in NGC 1316
Kristen C. Dage, Arunav Kundu, Erica Thygesen +8
We have identified three ultraluminous X-ray sources (ULXs) hosted by globular clusters (GCs) within NGC 1316's stellar system. These discoveries bring the total number of known UL…
X-Ray Spectroscopy of Newly Identified ULXs Associated With M87's Globular Cluster Population
Kristen C. Dage, Stephen E. Zepf, Erica Thygesen +5
We have identified seven ultraluminous X-ray sources (ULXs) which are coincident with globular cluster candidates (GCs) associated with M87. ULXs in the old GC environment represen…
