Designing miniature x-ray optics for the SmallSat lunar science mission concept CubeX [PDF]

, 2020
Planetary remote-sensing instruments are often required to cover a relatively large field of view, ideally with a uniform angular resolution over the field, due to relatively large apparent sizes of planetary targets at close proximities.

X-Ray and optical observations of the X-ray source EX0020528+1454.8 [PDF]

Astrophysics and Space Science, 1987
AbstractWe present preliminary results of the EXOSAT X-ray observations and quasisimultaneous and simultaneous optical photometry of the X-ray source EX0020528+1454.8 = 1E0205+149 found independently as an serendipitous source both with Einstein and EXOSAT satellites.

Characterization and compression of sub-10 fs UV pulses using dispersion scan [PDF]

EPJ Web of Conferences
We generated sub-10 fs transform-limited deep-UV pulses at approximately 260 nm via resonant dispersive-wave emission. Pulse compression and full characterization were achieved using an XPW d-scan system based on a 4-f pulse stretcher/compressor.

Apochromatic X-ray focusing

Light: Science & Applications, 2023
Achromatic doublets are combinations of two individual lenses designed to focus different wavelengths of light in the same position. Apochromatic optics are improved versions of the achromatic schemes which extend the wavelength range significantly. Both

Creation and annihilation of topological meron pairs in in-plane magnetized films

Nature Communications, 2019
A meron is one half of a skyrmion but whether a single meron pair can be created and stabilized remains a challenging question. Here, Gao et al. develop a method to create and stabilize individual pairs of merons in a continuous Py film by local vortex ...

The ATHENA telescope and optics status

, 2022
Paper 103990BThe work on the definition and technological preparation of the ATHENA (Advanced Telescope for High ENergy Astrophysics) mission continues to progress. In parallel to the study of the accommodation of the telescope, many aspects of the X-ray
