Modulation-frequency encoded multi-wavelength fluorescence analysis [PDF]
, 2011 We introduce a principle of parallel optical processing: modulation-frequency-encoded multi-wavelength laser excitation, fluorescence detection with a single detector, and Fourier analysis decoding. As an example, we demonstrate simultaneous detection of

From SN 2010da to NGC 300 ULX-1: Ten Years of Observations of an Unusual High Mass X-Ray Binary in NGC 300 [PDF]
, 2020 In May 2010, an intermediate luminosity optical transient was discovered in the nearby galaxy NGC 300 by a South African amateur astronomer. In the decade since its discovery, multi-wavelength observations of the misnamed “SN 2010da” have continually ...

Lomonosov GRB Catalogue: The First Experience of Prompt Emission Multi-Wavelength Observations
Universe, 2021 This paper presents a catalogue of gamma-ray bursts (GRBs) that were detected by the instruments onboard the Lomonosov space observatory. The Lomonosov mission gave the first experience of not only multi-wavelength (from optical to gamma) observations of

Multi-Wavelength Spatiotemporal Mode-Locked Fiber Laser at 1.55 μm
Photonics, 2022 We propose and demonstrate an effective and simple multi-wavelength spatiotemporal mode-locked (STML) laser. The laser introduces a multimode interference (MMI) effect using the core diameter mismatch of the fibers, thus enabling simultaneous mode ...

Multi-Wavelength Study of 4C+28.07 [PDF]
The Astrophysical Journal, 2021 Abstract 4C+28.07 is a γ-ray flat-spectrum-radio-quasar-type source. It is often monitored at different frequencies, though long-term multi-wavelength data of this source have not been modeled in detail before. We have analyzed ∼12 yr (2008 August–2020 May) of Fermi-LAT data with a binning of 10 day timescale and observed three ...

Performance Analysis of Three-Wavelength Multi-Channel Photonic Crystal Filters of Different Sizes
Crystals, 2022 Multi-wavelength and multi-channel photonic crystal filters are designed with different sizes considered by using a two-dimensional quadric lattice photonic crystal structure to solve the problems of a multi-channel filter with structure complexity ...

Multi-wavelength Behaviour of III Zw2 [PDF]
Publications of the Astronomical Society of Australia, 2002 AbstractIII Zw2 was observed with XMM-Newton in July 2000. Its X-ray spectrum can be described by a power law of photon index Γ≈1.7 with a Gaussian line at 6.7 KeV. There is no significant evidence of intrinsic absorption within the source or of a soft X-ray excess.
