SDSS-IV MaNGA: Spectroscopic Probes of Neutral Gas in Nearby Galaxies Open

Camilo Machuca, Matthew A. Bershady, Kate H. R. Rubin, Eric Wilcots · 2025

Cool, dusty interstellar material plays an important role in the chemical evolution of galaxies. We present an analysis of this material across galaxy type through a spatially resolved spectral stacking analysis of galaxies from the MaNGA …

SDSS-IV MaNGA: calibration of astrophysical line-widths in the Hα region using HexPak observations Open

Sabyasachi Chattopadhyay, Matthew A. Bershady, David R. Law, Kyle B. Westfall, Shravan Shetty , et al. · 2024

We have re-observed $\rm \sim$40 low-inclination, star-forming galaxies from the MaNGA survey (σ ∼ 65 km s−1) at ∼6.5 times higher spectral resolution (σ ∼ 10 km s−1) using the HexPak integral field unit on the WIYN 3.5-m telescope. The ai…

Sabyasachi Chattopadhyay, Matthew A. Bershady, David R. Law, Kyle B. Westfall, Shravan Shetty , et al. · 2024

We have re-observed $\rm\sim$40 low-inclination, star-forming galaxies from the MaNGA survey ($\upsigma\sim65$~\kms) at $\sim$6.5 times higher spectral resolution ($\upsigma\sim10$~\kms) using the HexPak integral field unit on the WIYN 3.5…

Gemini Near-Infrared Field Spectrograph Observations of the Seyfert 2 Galaxy Mrk 3: Feeding and Feedback on Galactic and Nuclear Scales Open

Crystal L. Gnilka, D. M. Crenshaw, Travis C. Fischer, Mitchell Revalski, Beena Meena , et al. · 2020

We explore the kinematics of the stars, ionized gas, and warm molecular gas in the Seyfert 2 galaxy Mrk 3 (UGC 3426) on nuclear and galactic scales with Gemini Near-Infrared Field Spectrograph observations, previous Hubble Space Telescope …

GEMINI NEAR INFRARED FIELD SPECTROGRAPH OBSERVATIONS OF THE SEYFERT 2 GALAXY MRK 573: IN SITU ACCELERATION OF IONIZED AND MOLECULAR GAS OFF FUELING FLOWS Open

Travis C. Fischer, Camilo Machuca, Marlon R. Diniz, D. M. Crenshaw, S. B. Kraemer , et al. · 2016

We present near-infrared and optical emission-line and stellar kinematics of the Seyfert 2 galaxy Mrk 573 using the Near-Infrared Field Spectrograph (NIFS) at Gemini North and Dual Imaging Spectrograph at Apache Point Observatory, respecti…
