Spectroscopic Constraints on the Build-up of the Intracluster Light in the Coma Cluster
Meng Gu, Charlie Conroy, David Law +13
The stellar content of the intracluster light (ICL) provides unique insight into the hierarchical assembly process of galaxy clusters.However, the ICL is difficult to study due to…
The Dragonfly Nearby Galaxies Survey. V. HST/ACS Observations of 23 Low Surface Brightness Objects in the Fields of NGC1052, NGC1084, M96, and NGC4258
Yotam Cohen, Pieter van Dokkum, Shany Danieli +8
We present HST/ACS imaging of twenty-three very low surface brightness (=25-27.5) galaxies detected in the fields of four nearby galaxy groups. These objects were selected…
A Revised Velocity for the Globular Cluster GC-98 in the Ultra Diffuse Galaxy NGC1052-DF2
Pieter van Dokkum, Yotam Cohen, Shany Danieli +9
We recently published velocity measurements of luminous globular clusters in the galaxy NGC1052-DF2, concluding that it lies far off the canonical stellar mass - halo mass relation…
The Maybe Stream: A Possible Cold Stellar Stream in the Ultra-Diffuse Galaxy NGC1052-DF2
Roberto Abraham, Shany Danieli, Pieter van Dokkum +10
We report tentative evidence for a cold stellar stream in the ultra-diffuse galaxy NGC1052-DF2. If confirmed, this stream (which we refer to as "The Maybe Stream") would be the fir…
An enigmatic population of luminous globular clusters in a galaxy lacking dark matter
Pieter van Dokkum, Yotam Cohen, Shany Danieli +10
We recently found an ultra diffuse galaxy (UDG) with a half-light radius of R_e = 2.2 kpc and little or no dark matter. The total mass of NGC1052-DF2 was measured from the radial v…
A galaxy lacking dark matter
Pieter van Dokkum, Shany Danieli, Yotam Cohen +9
Studies of galaxy surveys in the context of the cold dark matter paradigm have shown that the mass of the dark matter halo and the total stellar mass are coupled through a function…
CHANG-ES XI: Circular Polarization in the Cores of Nearby Galaxies
Judith A Irwin, Richard N. Henriksen, Marek Wezgowiec +18
We detect 5 galaxies in the CHANG-ES (Continuum Halos in Nearby Galaxies -- an EVLA Survey) sample that show circular polarization (CP) at L-band in our high resolution data sets.…
The dragonfly nearby galaxies survey. Iv. A giant stellar disk in ngc 2841
Jielai Zhang, Roberto Abraham, Pieter van Dokkum +2
Neutral gas is commonly believed to dominate over stars in the outskirts of galaxies, and investigations of the disk-halo interface are generally considered to be in the domain of…
