The 3-Dimensional Structure of NGC 891 and M51

open access: yes, 2012
We investigate the three-dimensional structure of the nearby edge-on spiral galaxy NGC 891 using 3D Monte Carlo radiative transfer models, with realistic spiral structure and fractally clumped dust.

A Calibration Method for Wide Field Multicolor Photometric System [PDF]

open access: yes, 1999
The purpose of this paper is to present a method to self-calibrate the spectral energy distribution (SED) of objects in a survey based on the fitting of an SED library to the observed multi-color photometry. We adopt for illustrative purposes the Vilnius

Irradiation of Astrophysical Objects - SED and Flux Effects on Thermally Driven Winds [PDF]

open access: yes, 2016
We develop a general method for the self consistent calculation of the hydrodynamics of an astrophysical object irradiated by a radiation field with an arbitrary strength and spectral energy distribution (SED).

Modelling and interpretation of SEDs [PDF]

open access: yesEPJ Web of Conferences, 2015
Circumstellar disks are mostly detected by larger continuum fluxes in the infrared to mm spectral regions as compared to naked stars (a flux excess). The analysis of the Spectral Energy Distribution (SED) of that flux excess was crucial for the development of the first theories about protoplanetary disks, and even nowadays, it is still one of the major

Ionic Metal Poly(heptazine Imides) and Single‐Atoms Interplay: Engineered Stability and Performance for Photocatalysis, Photoelectrocatalysis and Organic Synthesis

open access: yesAdvanced Functional Materials, EarlyView.
Poly(heptazine) imides (PHIs), a crystalline carbon nitride subclass, intercalate metals to deliver high stability, tunable electronics, and efficient charge separation. These features enable solar‐driven applications such as hydrogen evolution, CO₂ reduction, and organic synthesis.

SED fitting with MCMC: methodology and application to large galaxy surveys

open access: yes, 2012
We present GalMC (Acquaviva et al 2011), our publicly available Markov Chain Monte Carlo algorithm for SED fitting, show the results obtained for a stacked sample of Lyman Alpha Emitting galaxies at z ~ 3, and discuss the dependence of the inferred SED ...

Spectral Energy Distributions of Passive T Tauri Disks: Inclination [PDF]

open access: yes, 1998
We compute spectral energy distributions (SEDs) for passive T Tauri disks viewed at arbitrary inclinations. Semi-analytic models of disks in radiative and hydrostatic equilibrium are employed. Over viewing angles for which the flared disk does not occult
