Simulation of high-contrast polarimetric observations of debris disks with the Roman Coronagraph Instrument
Ramya M Anche, Ewan Douglas, Kian Milani +5
The Nancy Grace Roman Space Telescope Coronagraph Instrument will enable the polarimetric imaging of debris disks and inner dust belts in the optical and near-infrared wavelengths,…
Approaches to lowering the cost of large space telescopes
Ewan S Douglas, Greg Aldering, Greg W. Allan +26
New development approaches, including launch vehicles and advances in sensors, computing, and software, have lowered the cost of entry into space, and have enabled a revolution in…
RZ Piscium Hosts a Compact and Highly Perturbed Debris Disk
Kate Y. L. Su, Grant M. Kennedy, George H. Rieke +6
RZ Piscium (RZ Psc) is well-known in the variable star field because of its numerous, irregular optical dips in the past five decades, but the nature of the system is heavily debat…
Poke: An open-source ray-based physical optics platform
Jaren N. Ashcraft, Ewan S. Douglas, Daewook Kim +8
Integrated optical models allow for accurate prediction of the as-built performance of an optical instrument. Optical models are typically composed of a separate ray trace and diff…
NMF-based GPU accelerated coronagraphy pipeline
Sai Krishanth P. M., Ewan S. Douglas, Justin Hom +4
We present a generalized Non-negative factorization (NMF)-based data reduction pipeline for circumstellar disk and exoplanet detection. By using an adaptable pre-processing routine…
Estimation of polarization aberrations and their effect on the coronagraphic performance for future space telescopes
Ramya M Anche, Sebastiaan Y. Haffert, Jaren N Ashcraft +5
A major goal of proposed future space observatories, such as the Habitable World Observatory, is to directly image and characterize Earth-like planets around Sun-like stars to sear…
Polarimetric modeling and assessment of science cases for Giant Magellan Telescope-Polarimeter (GMT-Pol)
Ramya M Anche, Grant Williams, Hill Tailor +5
Polarization observations through the next-generation large telescopes will be invaluable for exploring the magnetic fields and composition of jets in AGN, multi-messenger transien…
Polarization aberrations in next-generation giant segmented mirror telescopes (GSMTs) I. Effect on the coronagraphic performance
Ramya M. Anche, Jaren N. Ashcraft, Sebastiaan Y. Haffert +8
Next-generation large segmented mirror telescopes are expected to perform direct imaging and characterization of Earth-like rocky planets, which requires contrast limits of $10^{-7…
