Simultaneous Estimation of Photometric Redshifts and SED Parameters: Improved Techniques and a Realistic Error Budget [PDF]
, 2015 We seek to improve the accuracy of joint galaxy photometric redshift estimation and spectral energy distribution (SED) fitting. By simulating different sources of uncorrected systematic errors, we demonstrate that if the uncertainties on the photometric ...

A probabilistic formulation of evolutionary synthesis models: implications for SED fittings [PDF]
, 2007 Evolutionary synthesis models (ESM) have been extensively used to obtain the star formation history in galaxies by means of SED fitting. Implicit in this use of ESM is that (a) for given evolutionary parameters, the shape of the SED is fixed whatever the

The Spectral Energy Distributions of Active Galactic Nuclei [PDF]
Proc. IAU 15 (2019) 21-25, 2019 We present ongoing work on the spectral energy distributions (SEDs) of active galactic nuclei (AGNs), derived from X-ray, ultraviolet, optical, infrared and radio photometry and spectroscopy. Our work is motivated by new wide-field imaging surveys that will identify vast numbers of AGNs, and by the need to benchmark AGN SED fitting codes.

A model for the infrared dust emission from forming galaxies [PDF]
, 2005 In the early epoch of galaxy evolution, dust is only supplied by supernovae (SNe). With the aid of a new physical model of dust production by SNe developed by Nozawa et al.

Can we constrain galaxy geometry parameters using spatially integrated SED fitting? [PDF]
, 2022 Sophisticated spectral energy distribution (SED) models describe dust attenuation and emission using geometry parameters. This treatment is natural since dust effects are driven by the underlying star-dust geometry in galaxies. An example is the Starduster SED model, which divides a galaxy into a stellar disk, a stellar bulge, and a dust disk.

Level and correlates of physical activity and sedentary behavior in patients with type 2 diabetes: a cross-sectional analysis of the italian diabetes and exercise study-2 [PDF]
, 2017 OBJECTIVE: Patients with type 2 diabetes usually show reduced physical activity (PA) and increased sedentary (SED)-time, though to a varying extent, especially for low-intensity PA (LPA), a major determinant of daily energy expenditure that is not ...

Panchromatic SED fitting codes and modelling techniques [PDF]
Proc. IAU 15 (2019) 26-34, 2019 Modelling and interpreting the SEDs of galaxies has become one of the key tools at the disposal of extragalactic astronomers. Ideally, we could hope that, through a detailed study of its SED, we can infer the correct physical properties and the evolutionary history of a galaxy. In the past decade, panchromatic SED fitting, i.e.
