Hace 2 días · The Dragonfly Spectral Line Mapper is an innovative all-refracting telescope designed to carry out ultra-low surface brightness wide-field mapping of visible wavelength line emission. ... λ 𝜆 \lambda italic_λ 5007 line emission produced by structures with sizes ranging from ∼ similar-to \sim ∼ 1 to 1000 kpc in the local ...
Hace 1 día · Both BODIPY 1 and BODIPY 2 distinguished by bathochromically shifted absorption and emission bands compared to their non-fused derivatives, while possessing green (526 – 543 nm) and red (664 – 708 nm) absorbance and fluorescence, respectively.
Hace 1 día · The spectral class of a star is a short code primarily summarizing the ionization state, giving an objective measure of the photosphere's temperature. Most stars are currently classified under the Morgan–Keenan (MK) system using the letters O , B , A , F , G , K , and M , a sequence from the hottest ( O type) to the coolest ( M type).
14 de jun. de 2024 · In a different approach, Yan et al. proposed a two-stage fast Bayesian spectral density method. By leveraging the assumption that the trace of the power spectral density matrix approximately follows a normal distribution, this method achieves decoupling of mode shapes from other modal parameters in cases of separated and dense modes.
7 de jun. de 2024 · The reconstructed audio from this spectral codec has perceptual quality comparable to audio codecs when evaluated on speech, while creating a discrete latent space that is easier for speech synthesis models to predict. We show that with a spectral codec, non-autoregressive TTS models can synthesize high-quality high-resolution audio.
20 de jun. de 2024 · The resulting coatings are sensitive to relative humidity variations, leading to a shift of their optical spectra called spectral shift. This spectral shift is generally observed on a narrow range, near the operating wavelength. Here we extend the concept of spectral shift to a broader spectral range. This analysis serves as a tool to study the ...
6 de jun. de 2024 · Tanager-1 will be the first of a next-generation hyperspectral fleet which will expand Planet’s imaging capabilities in the spectral domain to complement the existing imaging capabilities in the temporal and spatial domains offered by the PlanetScope, SkySat, and Pelican missions.
