Journal ArticleDOI
A Search for Molecular Gas in the Nucleus of M87 and Implications for the Fueling of Supermassive Black Holes
TL;DR: In this paper, the authors estimate a conservative upper limit on the mass of molecular gas within 100 pc and ±400 km s−1 line-of-sight velocity of the central black hole of the giant elliptical galaxy M87, including an allowance for possible systematic errors associated with subtraction of the continuum.
Journal ArticleDOI
THE GALAXY ENVIRONMENT OF A QSO AT z ∼ 5.7
Eduardo Bañados,Bram Venemans,Fabian Walter,Jaron Kurk,Roderik Overzier,Masami Ouchi,Masami Ouchi +6 more
TL;DR: In this paper, the authors used deep narrow-and broadband imaging to study the environment of the z = 5.72 quasar ULAS J0203+0012 and found no enhancement of Lyman alpha emitters (LAEs) in comparison with blank fields.
Journal ArticleDOI
The Green Bank Telescope Maps the Dense, Star-forming Gas in the Nearby Starburst Galaxy M82
Amanda A. Kepley,Adam K. Leroy,David T. Frayer,Antonio Usero,J. Marvil,J. Marvil,Fabian Walter +6 more
TL;DR: In this article, the authors demonstrate the power of the Byrd Green Bank Telescope (GBT) for mapping dense gas in galaxies by presenting the most sensitive maps yet of HCN and HCO+ in the starburst galaxy M82.
Journal ArticleDOI
High-resolution spectroscopic imaging of CO in a z=4.05 proto-cluster
Jacqueline Hodge,Chris Carilli,Fabian Walter,Fabian Walter,Emanuele Daddi,Dominik A. Riechers,Dominik A. Riechers +6 more
TL;DR: In this article, the formation of massive galaxies at large look-back times via spectroscopic imaging of CO in the unique GN20 proto-cluster at z = 4.05 was studied.
Journal ArticleDOI
No evidence for [CII] halos or high-velocity outflows in z>6 quasar host galaxies
Mladen Novak,Bram Venemans,Fabian Walter,Marcel Neeleman,Melanie Kaasinen,Lichen Liang,Robert Feldmann,Eduardo Bañados,Chris Carilli,Roberto Decarli,Alyssa B. Drake,Xiaohui Fan,Emanuele Paolo Farina,Chiara Mazzucchelli,Hans-Walter Rix,Ran Wang +15 more
TL;DR: In this paper, the authors investigated the interstellar medium in a sample of 27 high-redshift quasar host galaxies at z>6, using the [CII] 158um emission line and the underlying dust continuum observed at 1kpc resolution with ALMA.
