Molecular Gas Inflows and Outflows in Ultraluminous Infrared Galaxies at and one QSO at
R. Herrera-Camus, E. Sturm, J. Graciá-Carpio +12
Aims. We aim to search and characterize inflows and outflows of molecular gas in four ultraluminous infrared galaxies (ULIRGs) at and one distant QSO at . Me…
Peering into the formation history of beta Pictoris b with VLTI/GRAVITY long baseline interferometry
GRAVITY Collaboration, M. Nowak, S. Lacour +65
Our objective is to estimate the C/O ratio in the atmosphere of beta Pictoris b and obtain an estimate of the dynamical mass of the planet, as well as to refine its orbital paramet…
An image of the dust sublimation region in the nucleus of NGC 1068
GRAVITY Collaboration, O. Pfuhl, R. Davies +40
We present near-infrared interferometric data on the Seyfert 2 galaxy NGC 1068, obtained with the GRAVITY instrument on the European Southern Observatory Very Large Telescope Inter…
AGN feedback in a galaxy merger: Multi-phase, galaxy-scale outflows including a fast molecular gas blob ~6 kpc away from IRAS F08572+3915
R. Herrera-Camus, A. Janssen, E. Sturm +12
To understand the role that AGN feedback plays in galaxy evolution we need in-depth studies of the multi-phase structure and energetics of galaxy-wide outflows. In this work we pre…
Molecular outflows in local galaxies: Method comparison and a role of intermittent AGN driving
D. Lutz, E. Sturm, A. Janssen +17
We report new detections and limits from a NOEMA and ALMA CO(1-0) search for molecular outflows in 13 local galaxies with high FIR surface brightness, and combine with results from…
The GRAVITY Young Stellar Object survey -- I. Probing the disks of Herbig Ae/Be stars in terrestrial orbits
K. Perraut, L. Labadie, B. Lazareff +69
The formation and the evolution of protoplanetary disks are important stages in the lifetime of stars. The processes of disk evolution and planet formation are intrinsically linked…
The KMOS^3D Survey: data release and final survey paper
E. Wisnioski, N. M. Förster Schreiber, M. Fossati +28
We present the completed KMOS survey an integral field spectroscopic survey of 739, , galaxies at using the K-band Multi…
Plateau de Bure High-z Blue-Sequence Survey 2 (PHIBSS2): Search for Secondary Sources, CO Luminosity Functions in the Field, and the Evolution of Molecular Gas Density through Cosmic Time
Laura Lenkić, Alberto D. Bolatto, Natascha M. Förster Schreiber +8
We report on the results of a search for serendipitous sources in CO emission in 110 cubes targeting CO(2-1), CO(3-2), and CO(6-5) at z ~ 1-2 from the second Plateau de Bure High-z…
The multiphase gas structure and kinematics in the circumnuclear region of NGC 5728
T. Taro Shimizu, R. I. Davies, D. Lutz +22
We report on our combined analysis of HST, VLT/MUSE, VLT/SINFONI, and ALMA observations of the local Seyfert 2 galaxy, NGC 5728 to investigate in detail the feeding and feedback of…
Resolved Molecular Gas and Star Formation Properties of the Strongly Lensed z=2.26 Galaxy SDSS J0901+1814
Chelsea E. Sharon, Amitpal S. Tagore, Andrew J. Baker +8
We present ~1" resolution (~2 kpc in the source plane) observations of the CO(1-0), CO(3-2), Halpha, and [N II] lines in the strongly-lensed z=2.26 star-forming galaxy SDSS J0901+1…
A spectroscopic study of a rich cluster at z=1.52 with Subaru LBT: the environmental impacts on the mass-metallicity relation
Shigeru V. Namiki, Yusei Koyama, Masao Hayashi +9
We present the results of our near-infrared (NIR) spectroscopic observations of a rich cluster candidate around a radio galaxy at (4C65.22) with Subaru/MOIRCS and LBT/LUCI…
First direct detection of an exoplanet by optical interferometry; Astrometry and K-band spectroscopy of HR8799 e
S. Lacour, M. Nowak, J. Wang +85
To date, infrared interferometry at best achieved contrast ratios of a few times on bright targets. GRAVITY, with its dual-field mode, is now capable of high contrast obs…
Test of Einstein equivalence principle near the Galactic center supermassive black hole
A. Amorim, M. Bauböck, J. P. Berger +49
During its orbit around the four million solar mass black hole Sagittarius A* the star S2 experiences significant changes in gravitational potential. We use this change of potentia…
Envisioning the next decade of Galactic Center science: a laboratory for the study of the physics and astrophysics of supermassive black holes
Tuan Do, Andrea Ghez, Jessica R. Lu +38
As the closest example of a galactic nucleus, the Galactic center (GC) presents an exquisite laboratory for learning about supermassive black holes (SMBH) and their environment. We…
