Effects of scattering and dust grain size on the temperature structure of protoplanetary discs: A three-layer approach
Akio K. Inoue, Akinori Oka, Taishi Nakamoto
The temperature in the optically thick interior of protoplanetary discs is essential for the interpretation of millimeter observations of the discs, for the vertical structure of t…
Intergalactic dust and its photoelectric heating
Akio K. Inoue, Hideyuki Kamaya
We have examined the dust photoelectric heating in the intergalactic medium (IGM). The heating rate in a typical radiation field of the IGM is represented by $Γ_{\rm pe} = 1.2\time…
A Monte Carlo simulation of the intergalactic absorption and the detectability of the Lyman continuum from distant galaxies
Akio K. Inoue, Ikuru Iwata
We have made a Monte Carlo simulation of the intergalactic absorption in order to model the Lyman continuum absorption, which is required to estimate the escape fraction of the Lym…
Observational Possibility of the "Snow Line" on the Surface of Circumstellar Disks with the Scattered Light
Akio K. Inoue, Mitsuhiko Honda, Taishi Nakamoto +1
We discuss how we obtain the spatial distribution of ice on the surface of the circumstellar disk around young stars. Ice in the disks plays a very important role in various issues…
UV dust attenuation in spiral galaxies: the role of age-dependent extinction and of the IMF
P. Panuzzo, G. L. Granato, V. Buat +4
We analyse the attenuation properties of a sample of UV selected galaxies, with the use of the spectrophotometric model Grasil. In particular, we focus on the relation between dust…
Escape fraction of ionizing photons from galaxies at z=0--6
Akio K. Inoue, Ikuru Iwata, Jean-Michel Deharveng
The escape fraction of ionizing photons from galaxies is a crucial quantity controlling the cosmic ionizing background radiation and the reionization. Various estimates of this par…
Competition between dust scattering albedo and 2175 A bump for ultraviolet colours of nearby disc galaxies
Akio K. Inoue
Observed ultraviolet (UV) colours of nearby disc galaxies show a reddening relative to their expected intrinsic colours. Since the 2175 Åbump found in the Milky Way's dust extincti…
Effects of dust scattering albedo and 2175 A bump on ultraviolet colours of normal disc galaxies
Akio K. Inoue, Veronique Buat, Denis Burgarella +3
We discuss dust properties in the interstellar medium (ISM) of nearby normal galaxies, by comparing observations in the ultraviolet (UV) with simulations by a radiative transfer mo…
Attenuation law of normal disc galaxies with clumpy distributions of stars and dust
Akio K. Inoue
We investigate the attenuation law seen through an interstellar medium (ISM) with clumpy spatial distributions of stars and dust. The clumpiness of the dust distribution is introdu…
Amount of intergalactic dust: constraints from distant supernovae and thermal history of intergalactic medium
Akio K. Inoue, Hideyuki Kamaya
This paper examines the allowed amount of IG (intergalactic) dust, which is constrained by extinction and reddening of distant SNe and thermal history of IGM (intergalactic medium)…
GRB Formation Rates inferred from the Spectral Peak Energy - Luminosity Relation
D. Yonetoku, T. Murakami, T. Nakamura +3
We investigate the GRB formation rate based on the relation between the spectral peak energy () and the isotropic luminosity. The --luminosity relation covers the ene…
Evolution of Dust-to-Metal Ratio in Galaxies
Akio K. Inoue
This paper investigates the evolution of the dust-to-metal ratio in galaxies based on a simple evolution model for the amount of metal and dust with infall. We take into account gr…
Near-Infrared Colors of Gamma-Ray Burst Afterglows and Cosmic Reionization History
Akio K. Inoue, Ryo Yamazaki, Takashi Nakamura
Using the near-infrared (NIR) observations of the afterglows of the high redshift ($5 \la z \la 25$) gamma-ray bursts (GRBs) which will be detected by the {\it Swift} satellite, we…
Constraint on intergalactic dust from thermal history of intergalactic medium
Akio K. Inoue, Hideyuki Kamaya
This Letter investigates the amount of dust in the intergalactic medium (IGM). The dust photoelectric heating can be the most efficient heating mechanism in the IGM where the densi…
The UV (GALEX) and FIR (ASTRO-F) All Sky Surveys: the measure of the dust extinction in the local universe
V. Buat, T. T. Takeuchi, A. Boselli +9
Before the end of 2002 will be launched the GALEX satellite (a NASA/SMEX project) which will observe all the sky in Ultraviolet (UV) through filters at 1500 and 2300 A down to m(AB…
Star Formation Rate from Dust Infrared Emission
Akio K. Inoue
We examine what types of galaxies the conversion formula from dust infrared (IR) luminosity into the star formation rate (SFR) derived by Kennicutt (1998) is applicable to. The rat…
Spatial Distribution of Dust Grains within H II Regions
Akio K. Inoue
We discuss the dust distribution within photoionized regions. Assuming a geometry with a central dust cavity, which is strongly suggested by the literature, we can estimate the cav…
