PROBES-I: A Compendium of Deep Rotation Curves and Matched multiband Photometry

TL;DR

PROBES-I provides an extensive collection of rotation curves and multiband photometry for late-type spirals, enabling detailed studies of galaxy structure and formation.

Contribution

It introduces a large, homogeneous dataset of rotation curves and photometry for over 3000 galaxies, combining multiple surveys and advanced photometric analysis tools.

Findings

Median rotation curves extend to 2R_e or 1R_{23.5, r}

Deep multiband photometry reaches magnitudes >25 mag/arcsec^2

Dataset supports diverse galaxy structure and formation studies

Abstract

We present the Photometry and Rotation Curve Observations from Extragalactic Surveys (PROBES) compendium of extended rotation curves for 3163 late-type spirals, with matching homogeneous multiband photometry for 1677 of them. PROBES rotation curves originally extracted from Halpha long-slit spectra and aperture synthesis HI (21cm) velocity maps typically extend out to a median 2R_e (or 1R_{23.5, r}). Our uniform photometry takes advantage of GALEX, DESI-LIS, and WISE images and the software AutoProf to yield multiband azimuthally averaged surface brightness profiles that achieve depths greater than 25 mag/arcsec^2 (FUV, NUV), 27 mag/arcsec^2 (g, r), and 26 mag/arcsec^2 (z, W1, W2). With its library of spatially resolved profiles and an extensive table of structural parameters, the versatile PROBES data set will benefit studies of galaxy structure and formation.
