Extraplanar [C II] and Halpha in the Edge-On Galaxy NGC 5775

William T. Reach, Dario Fadda, Richard J. Rand +1

Spiral galaxies are thin and susceptible to being disrupted vertically. The largest star clusters, and nuclear starbursts, generate enough energy from winds and supernovae to send…

eDIG-CHANGES II: Project Design and Initial Results on NGC 3556

Jiang-Tao Li, Li-Yuan Lu, Zhijie Qu +19

The extraplanar diffuse ionized gas (eDIG) represents ionized gases traced by optical/UV lines beyond the stellar extent of galaxies. We herein introduce a novel multi-slit narrow-…

eDIG-CHANGES I: Extended Hα Emission from the Extraplanar Diffuse Ionized Gas (eDIG) around CHANG-ES Galaxies

Li-Yuan Lu, Jiang-Tao Li, Carlos J. Vargas +14

The extraplanar diffuse ionized gas (eDIG) represents the cool/warm ionized gas reservoir around galaxies. We present a spatial analysis of H images of 22 nearby edge-on spiral…

The Volumetric Star Formation Law in the Almost Edge-on Galaxy NGC 4302 Revealed by ALMA

Kijeong Yim, Tony Wong, Richard J. Rand

We observe the almost edge-on (i 90 degrees) galaxy NGC 4302 using ALMA (CO) and VLA (H I) to measure the gas disk thickness for investigating the volumetric star formation…

HALOGAS: Strong Constraints on the Neutral Gas Reservoir and Accretion Rate in Nearby Spiral Galaxies

P. Kamphuis, E. Jütte, G. H. Heald +11

Galaxies in the local Universe are thought to require ongoing replenishment of their gas reservoir in order to maintain the observed star formation rates. Cosmological simulations…

CHANG-ES XXIII: Influence of a galactic wind in NGC 5775

G. H. Heald, V. Heesen, S. S. Sridhar +22

We present new radio continuum images of the edge-on starburst galaxy NGC 5775, from LOFAR (140 MHz) and the Karl G. Jansky Very Large Array CHANG-ES survey (1500 MHz). We trace th…
