Extended Line Emission in the BCG of Abell 2390
Leo Y. Alcorn, H. K. C Yee, Laurent Drissen +10
We report CFHT/SITELLE imaging Fourier Transform Spectrograph observations of the Brightest Cluster Galaxy (BCG) of galaxy cluster Abell 2390 at z=0.228. The BCG displays a promine…
A Nascent Tidal Dwarf Galaxy Forming within the Northern HI Streamer of M82
Imad Pasha, Deborah Lokhorst, Pieter G. van Dokkum +12
We identify a 600 pc-wide region of active star formation located within a tidal streamer of M82 via emission ( erg s cm), us…
A Method To Characterize the Wide-Angle Point Spread Function of Astronomical Images
Qing Liu, Roberto Abraham, Colleen Gilhuly +14
Uncertainty in the wide-angle Point Spread Function (PSF) at large angles (tens of arcseconds and beyond) is one of the dominant sources of error in a number of important quantitie…
Tidal Distortions in NGC1052-DF2 and NGC1052-DF4: Independent Evidence for a Lack of Dark Matter
Michael A. Keim, Pieter van Dokkum, Shany Danieli +11
Two ultra diffuse galaxies in the same group, NGC1052-DF2 and NGC1052-DF4, have been found to have little or no dark matter and to host unusually luminous globular cluster populati…
SITELLE Hα Imaging Spectroscopy of z~0.25 Clusters: Emission Line Galaxy Detection and Ionized Gas Offset in Abell 2390 & Abell 2465
Qing Liu, Howard Yee, Laurent Drissen +9
Environmental effects are crucial to the understanding of the evolution of galaxies in dense environments, such as galaxy clusters. Using the large field-of-view of SITELLE, the un…
Dust Attenuation Curve for Local Subgalactic Star-forming Regions
Berzaf B. Teklu, Zesen Lin, Xu Kong +5
We compile a sample of about 157,000 spaxels from the Mapping Nearby Galaxies at the Apache Point Observatory survey to derive the average dust attenuation curve for subgalactic st…
The Dragonfly Wide Field Survey. I. Telescope, Survey Design and Data Characterization
Shany Danieli, Deborah Lokhorst, Jielai Zhang +11
We present a description of the Dragonfly Wide Field Survey (DWFS), a deep photometric survey of a wide area of sky. The DWFS covers 330 in the equatorial GAMA fie…
Multi-resolution filtering: an empirical method for isolating faint, extended emission in Dragonfly data and other low resolution images
Pieter van Dokkum, Deborah Lokhorst, Shany Danieli +5
We describe an empirical, self-contained method to isolate faint, large-scale emission in imaging data of low spatial resolution. Multi-resolution filtering (MRF) uses independent…
The Dragonfly Edge-on Galaxies Survey: Shaping the outer disc of NGC 4565 via accretion
Colleen Gilhuly, David Hendel, Allison Merritt +6
We present extremely deep imaging of the well-known edge-on galaxy NGC 4565 (the "Needle Galaxy"), observed as part of the Dragonfly Edge-on Galaxies Survey. Our imaging traces sta…
What determines the local metallicity of galaxies: global stellar mass, local stellar mass surface density or star formation rate?
Yulong Gao, Enci Wang, Xu Kong +8
The metallicity and its relationship with other galactic properties is a fundamental probe of the evolution of galaxies. In this work, we select about 750,000 star-forming spatial…
Elevation or Suppression? The Resolved Star Formation Main Sequence of Galaxies with Two Different Assembly Modes
Qing Liu, Enci Wang, Zesen Lin +4
We investigate the spatially-resolved star formation main sequence in star-forming galaxies (SFGs) using Integral Field Spectroscopic (IFS) observations from the Mapping Nearby Gal…
The Properties of Massive Star-forming galaxies with Outside-in Assembly Mode
Enci Wang, Xu Kong, Huiyuan Wang +4
Previous findings show that massive () star-forming (SF) galaxies usually have an inside-out stellar mass assembly mode. In this paper, we have for the first tim…
