Toward blazed UV gratings for the Habitable Worlds Observatory and beyond

Drew M. Miles, Jake McCoy, Fabien Grisé, Randall L. McEntaffer

The Habitable Worlds Observatory (HWO) and other future missions require advancements in component technologies to achieve their science objectives. We discuss here several techniques developed through the Strategic Astrophysics Technologies program to manufacture blazed gratings for ultraviolet (UV) spectroscopy. Prototype gratings fabricated …

Great Observatories Maturation: a Review of NASA Astrophysics Development Through Suborbital Rocket and Balloon Programs

Drew M. Miles

The NASA Great Observatories Maturation Program is a development plan to efficiently and effectively develop large, strategic astrophysics missions. Suborbital rocket and balloon programs have long been a key development tool for enabling large missions in NASA astrophysics. We review the significance …

Reflection grating fabrication for the Rockets for Extended-source X-ray Spectroscopy

Drew M. Miles, Ross McCurdy, Michael Labella, Randall L. McEntaffer et autres

Abstract The Rockets for Extended-source X-ray Spectroscopy (tREXS) grating spectrograph uses modules of reflection gratings to collect spectroscopic data from extended astronomical sources of soft X-rays. Two blazed master gratings were produced on silicon substrates with electron-beam lithography (EBL) and complementary nanofabrication …

The Faint Intergalactic-medium Redshifted Emission Balloon (FIREBall-2)

Drew M. Miles, Vincent Picouet, Chris Martin, Erika Hamden et autres

The Faint Intergalactic Medium Redshifted Emission Balloon (FIREBall-2) is a UV multi-object spectrograph designed to detect emission from the circumgalactic and circumquasar medium at low redshifts (0.3 < z < 1.0). The FIREBall-2 spectrograph uses a suborbital balloon vehicle to access a …

FIREBall-2 UV balloon telescope in-flight calibration system

Jessica Li, Nazende I. Kerkeser, Aafaque R. Khan, Simran Agarwal et autres

We present the integration of a new calibration system into the Faint Intergalactic-medium Redshifted Emission Balloon-2 (FIREBall-2), which added in-flight calibration capability for the recent September 2023 flight. This system is composed of a calibration source box containing zinc and deuterium lamp …

Balloon-borne FIREBall-2 ultraviolet spectrograph stray light control based on nonsequential reverse modeling of on-sky data

Trenton Brendel, Aafaque R. Khan, Simran Agarwal, Heejoo Choi et autres

We present a comprehensive stray light analysis and mitigation strategy for the FIREBall-2 ultraviolet balloon telescope. Using nonsequential optical modeling, we identified the most problematic stray light paths, which impacted telescope performance during the 2018 flight campaign. After confirming the correspondence between …
