The nature of massive black hole binary candidates: II. Spectral energy distribution atlas

Elisabeta Lusso, Roberto Decarli, Massimo Dotti +5

Recoiling supermassive black holes (SMBHs) are considered one plausible physical mechanism to explain high velocity shifts between narrow and broad emission lines sometimes observe…

The Gaia astrophysical parameters inference system (Apsis). Pre-launch description

C. A. L. Bailer-Jones, R. Andrae, B. Arcay +46

The Gaia satellite will survey the entire celestial sphere down to 20th magnitude, obtaining astrometry, photometry, and low resolution spectrophotometry on one billion astronomica…

The nature of massive black hole binary candidates: I. Spectral properties and evolution

Roberto Decarli, Massimo Dotti, Michele Fumagalli +5

Theoretically, bound binaries of massive black holes are expected as the natural outcome of mergers of massive galaxies. From the observational side, however, massive black hole bi…

A data-driven model for spectra: Finding double redshifts in the Sloan Digital Sky Survey

P. Tsalmantza, David W. Hogg

We present a data-driven method - heteroscedastic matrix factorization, a kind of probabilistic factor analysis - for modeling or performing dimensionality reduction on observed sp…

A semi-empirical library of galaxy spectra for Gaia classification based on SDSS data and PEGASE models

P. Tsalmantza, A. Karampelas, M. Kontizas +6

Aims:This paper is the third in a series implementing a classification system for Gaia observations of unresolved galaxies. The system makes use of template galaxy spectra in order…

A systematic search for massive black hole binaries in SDSS spectroscopic sample

P. Tsalmantza, R. Decarli, M. Dotti +1

We present the results of a systematic search for massive black hole binaries in the Sloan Digital Sky Survey spectroscopic database. We focus on bound binaries, under the assumpti…
