MSA-3D: dissecting galaxies at z~1 with high spatial and spectral resolution
Ivana BariÅ¡iÄ, Tucker Jones, Kris Mortensen +18
Integral field spectroscopy (IFS) is a powerful tool for understanding the formation of galaxies across cosmic history. We present the observing strategy and first results of MSA-3…
Ionized gas in quiescent galaxies: Temperature measurement and constraint on the ionization source
Man-Yin Leo Lee, Renbin Yan, Xihan Ji +5
In non-star-forming, passively evolving galaxies, regions with emission lines dominated by low-ionization species are classified as Low-Ionization Emission Regions (LIERs). The ion…
SDSS-IV MaNGA: Stellar rotational support in disk galaxies vs. central surface density and stellar population age
Xiaohan Wang, Yifei Luo, S. M. Faber +10
We investigate how the stellar rotational support changes as a function of spatially resolved stellar population age () and relative central stellar surface density ($…
The Strength of Bisymmetric Modes in SDSS-IV/MaNGA Barred Galaxy Kinematics
Brian DiGiorgio Zanger, Kyle B. Westfall, Kevin Bundy +7
The SDSS-IV/MaNGA Survey data provide an unprecedented opportunity to study the internal motions of galaxies and, in particular, represent the largest sample of barred galaxy kinem…
Asymmetric drift in MaNGA: Mass and radially-dependent stratification rates in galaxy disks
Matthew A. Bershady, Kyle B. Westfall, Shravan Shetty +5
We measure the age-velocity relationship from the lag between ionized gas and stellar tangential speeds in ~500 nearby disk galaxies from MaNGA in SDSS-IV. Selected galaxies are ki…
SDSS-IV MaNGA: Calibration of astrophysical line-widths in the Hα region using HexPak observations
Sabyasachi Chattopadhyay, Matthew A. Bershady, David R. Law +7
We have re-observed 40 low-inclination, star-forming galaxies from the MaNGA survey ($\upsigma\sim65$~\kms) at 6.5 times higher spectral resolution ($\upsigma\sim10$…
