We used existing data from the New Horizons Long-range Reconnaissance Imager (LORRI) to measure the optical-band (0.4 ≲ λ ≲ 0.9 μm) sky brightness within seven high–Galactic latitude fields. The average raw level measured while New Horizons was 42–45 au from the Sun is 33.2 ± 0.5 nW m−2 sr−1. This is ∼10× as dark as the darkest sky accessible to the Hubble Space Telescope, highlighting the utility of New Horizons for detecting the cosmic optical background (COB). Isolating the COB contribution… 
Low-energy Quantum Gravity and Cosmology
The model of low-energy quantum gravity by the author is based on the conjecture about the existence of the background of super-strong in- teracting gravitons, gravity is considered as the screening
Can the zero-point energy of the quantized harmonic oscillator be lower? Possible implications for the physics of "dark energy" and "dark matter"
Replacing the canonical pair q and p of the harmonic oscillator (HO) by the locally and symplectically equivalent pair angle phi and action variable I implies a qualitative change of the global
An observational determination of the evolving extragalactic background light from the multiwavelength HST/CANDELS survey in the Fermi and CTA era
The diffuse extragalactic background light (EBL) is formed by ultraviolet (UV), optical, and infrared (IR) photons mainly produced by star formation processes over the history of the Universe and
A James Webb Space Telescope Deep Field Simulation Using a Geometric-Focused Ensemble Approach
The James Webb Space Telescope (JWST) is estimated to observe objects as far as z = 15 with a sensitivity 100 times that of the Hubble Space Telescope (HST). Several previous simulations have
Three different effects of the same quantum nature

  • Proceedings of The European Physical Society Conference on High Energy Physics — PoS(EPS-HEP2021)
  • 2022
In the model of low-energy quantum gravity by the author the cosmological redshift and additional dimming of remote objects may be interpreted as results of scattering of photons on gravitons of the
A new spacecraft mission concept combining the first exploration of the Centaurs and an astrophysical space telescope for the outer solar system
The mission design accomplishes its objectives using solar electric propulsion and the recently developed NASA Evolutionary Xenon Thruster (NEXT) ion engines and ride-along cubesats included aboard can be deployed at different points in the mission to perform various experiments or observations.
Photon–Photon Interactions and the Opacity of the Universe in Gamma Rays
We discuss the topic of the transparency of the Universe in gamma rays due to extragalactic background light, and its cosmological and physical implications. Rather than a review, this is a personal
Probing Intra-Halo Light with Galaxy Stacking in CIBER Images
We study the stellar halos of 0.2 ≲ z ≲ 0.5 galaxies with stellar masses spanning M * ∼ 1010.5 to 1012 M ⊙ (approximately L * galaxies at this redshift) using imaging data from the Cosmic Infrared
The quantum nature of gravity seen in cosmological observations
In the author’s model of low-energy quantum gravity, the cosmological redshift, additional darkening of distant objects and a diffuse cosmic optical background, presumably detected by the New


Long-Range Reconnaissance Imager on New Horizons
Abstract The LOng-Range Reconnaissance Imager (LORRI) is the high-resolution imaging instrument for the New Horizons mission to Pluto, its giant satellite Charon, its small moons Nix and Hydra, and
The Optical Extragalactic Background Light: Revisions and Further Comments
We revise the measurements in our previous work of foreground zodiacal light (ZL) and diffuse Galactic light (DGL) that were used to measure the extragalactic background light (EBL). These changes
In-flight Performance and Calibration of the LOng Range Reconnaissance Imager (LORRI) for the New Horizons Mission
The LOng Range Reconnaissance Imager (LORRI) is a panchromatic (360--910 nm), narrow-angle (field of view = 0.29 deg), high spatial resolution (pixel scale = 1.02 arcsec) visible light imager used on

The solar system currently possesses two remnant debris disks leftover from the planetary formation era in the form of the asteroid belt and the Edgeworth–Kuiper Belt (EKB). Similar to other stellar
Fluctuation of the background sky in the Hubble Extremely Deep Field (XDF) and its origin
We performed a fluctuation analysis of the Hubble Extremely Deep Field (XDF) at four optical wavelength bands and found large fluctuations that are significantly brighter than those expected for
