We have searched for continuous gravitational wave (CGW) signals produced by individually resolvable, circular supermassive black hole binaries (SMBHBs) in the latest EPTA dataset, which consists of...
View ArticleThe Thermal Design, Characterization, and Performance of the SPIDER...
We describe the SPIDER flight cryostat, which is designed to cool six millimeter-wavelength telescopes during an Antarctic long-duration balloon flight. The cryostat, one of the largest to have flown...
View ArticleOptimized Large-Scale CMB Likelihood And Quadratic Maximum Likelihood Power...
We revisit the problem of exact CMB likelihood and power spectrum estimation with the goal of minimizing computational cost through linear compression. This idea was originally proposed for CMB...
View ArticleReliable inference of exoplanet light curve parameters using deterministic...
Time-series photometry and spectroscopy of transiting exoplanets allow us to study their atmospheres. Unfortunately, the required precision to extract atmospheric information surpasses the design...
View ArticleExploiting the time of arrival of Cherenkov photons at the 28 m H.E.S.S....
In 2012, the High Energy Stereoscopic System (H.E.S.S.) was expanded by a fifth telescope (CT5). With an effective mirror diameter of 28m, CT5 is able to detect the Cherenkov light of very faint...
View ArticleEfficient, uninformative sampling of limb darkening coefficients for a...
Stellar limb darkening impacts a wide range of astronomical measurements. The accuracy to which it is modeled limits the accuracy in any covariant parameters of interest, such as the radius of a...

The realization of X-ray telescopes with imaging capabilities in the hard (> 10 keV) X-ray band requires the adoption of optics with shallow (< 0.25 deg) grazing angles to enhance the...
View ArticleCharacterization of a flat superpolished mandrel prototype with hard (TiN /...
A number of hard X-Ray (10 - 100 KeV) astronomical missions of near future will make use of multilayer-coated focusing mirrors. The technology based on Nickel electroformed replication is suitable for...
