One year of tropospheri clidar measurements of aerosol extinction and backscatter
lidar EARLINET aerosol
2015/9/16
The aerosol lidar system operational at IMAA-CNR in Tito Scalo (PZ) (Southern Italy, 40°36'N, 15°44'E, 820 m
above sea level) is part of the EARLINET project. Systematic lidar measurements of aerosol...
Gaps in the cloud cover? Comparing extinction measures in spiral disks
dust in galaxies spiral galaxies
2014/12/23
Dust in galaxies can be mapped either by the FIR/submillimeter emission, the optical or infrared reddening of starlight, or the extinction of a known background source. We compare two dust extinction ...
Intergalactic dust extinction in hydrodynamic cosmological simulations
formation intergalactic medium
2014/12/22
Recently Ménard et al. (hereafter MSFR) detected a subtle but systematic change in the mean colour of quasars as a function of their projected separation from foreground galaxies, extending to comovin...
The four HII regions in the Sgr A East complex: A, B, C, and D, represent evidence of recent massive star formation in the central ten parsecs. Using Paschen-alpha images taken with HST and 8.4 GHz VL...
Extinction law in ultraluminous infrared galaxies at z ~ 1
dust, extinction — galaxies: evolution — galaxies: ISM — galaxies: starburst — infrared: galaxies — supernovae: general
2011/10/17
We analyze the multi-wavelength photometric and spectroscopic data of 12 ultraluminous infrared galaxies (ULIRGs) at z ~ 1 and compare them with models of stars and dust in order to study the extincti...
2MASS wide field extinction maps: IV. The Orion, Mon R2, Rosette, and Canis Major star forming regions
clouds dust extinction structure individual objects Orion molecular complex
2011/10/21
We present a near-infrared extinction map of a large region (approximately 2200 deg^2) covering the Orion, the Monoceros R2, the Rosette, and the Canis Major molecular clouds. We used robust and optim...
Deep Near-Infrared Survey of the Pipe Nebula II: Data, Methods, and Dust Extinction Maps
ISM clouds – infrared ISM –stars formation
2010/11/11
We present a new set of high resolution dust extinction maps of the nearby and essentially
starless Pipe Nebula molecular cloud. The maps were constructed from a concerted deep nearinfrared imaging s...
Supernova dust for the extinction law in a young infrared galaxy at z = 1
dust extinction — galaxies evolution — galaxies ISM — galaxies starburst — infrared galaxies — supernovae general
2010/11/10
We apply the supernova(SN) extinction curves to reproduce the observed properties of SST J1604+4304 which is a young infrared (IR) galaxy at z ∼ 1. The SN extinction curves used in this work wer...
WINGS-SPE II: A catalog of stellar ages and star formation histories, stellar masses and dust extinction values for local clusters galaxies
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
The WIde-field Nearby Galaxy clusters Survey (WINGS) is a project whose primary goal is to study the galaxy populations in clusters in the local universe (z<0.07) and of the influence of environment o...
Three-Component Dust Models for Interstellar Extinction
Dust extinction—ISM abundances—ISM
2010/9/15
Interstellar extinction curves obtained from the ‘extinction without standard’ method were used to constrain the dust characteristics in the mean ISM (RV = 3.1), along the lines of sight through a hig...

DUST PLASMA ANALOGUE FOR INTERSTELLAR 217.5 nm EXTINCTION
dust extinction-Methods laboratory
2009/1/16
The new ultraviolet (UV) extinction measurements of carbona-
ceous nanoparticles in the range from 140 nm to 260 nm are presented. The plasma
polymerized hydrocarbon nanoparticles were already propo...
