Photometric Signature of Ultra-Harmonic Resonances in Barred Galaxies
Dhanesh Krishnarao, Zachary J. Pace, Elena D'Onghia +11
Bars may induce morphological features, such as rings, through their resonances. Previous studies suggested that the presence of 'dark-gaps', or regions of a galaxy where the diffe…
The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar and APOGEE-2 Data
Abdurro'uf, Katherine Accetta, Conny Aerts +337
This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete…
HI-MaNGA: Tracing the physics of the neutral and ionized ISM with the second data release
David V. Stark, Karen L. Masters, Vladimir Avila-Reese +19
We present the second data release for the HI-MaNGA programme of HI follow-up observations for the SDSS-IV MaNGA survey. This release contains measurements for 3669 unique galaxies…
SDSS-IV/MaNGA: Can impulsive gaseous inflows explain steep oxygen abundance profiles \& anomalously-low-metallicity regions?
Zachary J. Pace, Christy Tremonti, Adam L. Schaefer +5
Gaseous inflows are necessary suppliers of galaxies' star-forming fuel, but are difficult to characterize at the survey scale. We use integral-field spectroscopic measurements of g…
The Effect of Bars on the Ionized ISM: Optical Emission Lines from Milky Way Analogs
Dhanesh Krishnarao, Christy Tremonti, Amelia Fraser-McKelvie +15
Gas interior to the bar of the Milky Way has recently been shown as the closest example of a Low Ionization (Nuclear) Emission Region--LI(N)ER--in the universe. To better understan…
SDSS-IV MaNGA: Variations in the N/O -- O/H relation bias metallicity gradient measurements
Adam L. Schaefer, Christy Tremonti, Francesco Belfiore +4
In this paper we use strong line calibrations of N/O and O/H in MaNGA spaxel data to explore the systematics introduced by variations in N/O on various strong-line metallicity diag…
