Flares and their echoes can help distinguish photon rings from black holes with space-Earth very long baseline interferometry
A. Andrianov, S. Chernov, I. Girin +3
Photon rings near the edge of a black hole shadow is supposed to be a unique tool to validate general relativity and provide reliable measurements of principal black hole parameter…
Time-of-Flight Photoelectron Momentum Microscopy at 100-500 MHz Synchrotron Sources: Electron-Optical Chopping or Bandwidth Pre-Selection
G. Schoenhense, K. Medjanik, O. Fedchenko +10
The small time gap of synchrotron radiation in conventional multi-bunch mode (100-500MHz) is prohibitive for time-of-flight (ToF) based electron spectroscopy. Even the new generati…
Hard X-ray Photoelectron Momentum Microscopy and Kikuchi Diffraction on (In,Ga,Mn)As Thin Films
K. Medjanik, O. Fedchenko, O. Yastrubchak +9
Recent advances in the brilliance of hard-X-ray beamlines and photoelectron momentum microscopy facilitate bulk valence-band mapping and core-level-resolved hard-X-ray photoelectro…
Band structure tuning of Heusler compounds revisited: Spin- and momentum-resolved electronic structure analysis of compounds with different band filling
S. Chernov, C. Lidig, O. Fedchenko +3
Spin-filtered time-of-flight photoelectron momentum microscopy reveals a systematic variation of the band structure within a series of highly spin-polarized ferromagnetic Heusler c…
Narrow-Band Pulsed Electron Source Based on Near-Threshold Photoionization of Cs in a Magneto-Optical Trap
O. Fedchenko, S. Chernov, G. Schönhense +2
The newly developed method of time-of-flight (ToF) momentum microscopy was used to analyse the cold electron emission from a Cs 3D magneto-optical trap (MOT). Three-step resonant p…
Breakthrough in HAXPES Performance Combining Full-Field k-Imaging with Time-of-Flight Recording
K. Medjanik, S. V. Babenkov, S. Chernov +8
We established a new approach to hard-X-ray photoelectron spectroscopy (HAXPES). The instrumental key feature is an increase of the dimensionality of the recording scheme from 2D t…
