Infrared spectroscopy has been developed significantly. In particular, infrared photons can be measured with high spectral and angular resolution in state-of-art spectrographs. They are sensitive to monochromatic photons due to the decay and annihilation of particles beyond the Standard Model, such as dark matter (DM), while insensitive to background photons that form a continuous spectrum. In this paper, we study the indirect detection of the DM decaying into infrared light using infrared…

Hadrophobic Axion from GUT

We propose a new kind of axion model from the Grand Unified Theory (GUT) based on SU(5) × U(1) PQ . We show that for a certain charge assignment and possible flavor models the axion is naturally

A GeV–TeV Measurement of the Extragalactic Background Light

The extragalactic background light (EBL) can be probed via the absorption imprint it leaves in the spectra of gamma-ray sources ( ). We recently developed a dedicated technique to reconstruct the

High sensitivity, wide coverage, and high-resolution NIR non-cryogenic spectrograph, WINERED

Near-infrared (NIR) high-resolution spectroscopy is a fundamental observational method in astronomy. It provides significant information on the kinematics, the magnetic fields, and the chemical

THE SPECTRUM OF THE DIFFUSE GALACTIC LIGHT: THE MILKY WAY IN SCATTERED LIGHT

We measure the optical spectrum of the diffuse Galactic light (DGL)—the local Milky Way in reflection—using 92,000 blank sky spectra from the Sloan Digital Sky Survey (SDSS). We correlate the SDSS

Anomalous Flux in the Cosmic Optical Background Detected with New Horizons Observations

We used New Horizons LORRI images to measure the optical-band (0.4 ≲ λ ≲ 0.9μm) sky brightness within a high-galactic-latitude field selected to have reduced diffuse scattered light from the Milky

AKARI OBSERVATION OF THE FLUCTUATION OF THE NEAR-INFRARED BACKGROUND

We report a search for fluctuations of the sky brightness toward the north ecliptic pole with the Japanese infrared astronomical satellite AKARI, at 2.4, 3.2, and 4.1 μm. We obtained circular maps

DWARF GALAXY ANNIHILATION AND DECAY EMISSION PROFILES FOR DARK MATTER EXPERIMENTS

Gamma-ray searches for dark matter annihilation and decay in dwarf galaxies rely on an understanding of the dark matter density profiles of these systems. Conversely, uncertainties in these density

Looking at cosmic near-infrared background radiation anisotropies

The cosmic infrared background (CIB) contains emissions accumulated over the entire history of the Universe, including from objects inaccessible to individual telescopic studies. The near-IR (~1-10

The COBE Diffuse Infrared Background Experiment Search for the Cosmic Infrared Background. II. Model of the Interplanetary Dust Cloud

The COBE Diffuse Infrared Background Experiment (DIRBE) was designed to search for the cosmic infrared background (CIB) radiation. For an observer confined to the inner solar system, scattered light

The COBE Diffuse Infrared Background Experiment Search for the Cosmic Infrared Background. III. Separation of Galactic Emission from the Infrared Sky Brightness

The Cosmic Infrared Background (CIB) is hidden behind veils of foreground emission from our own solar system and Galaxy. This paper describes procedures for removing the Galactic IR emission from the
