Project Dinos I: A joint lensing-dynamics constraint on the deviation from the power law in the mass profile of massive ellipticals
Treu, Tommaso; Sonnenfeld, Alessandro; Birrer, Simon +7 more
The mass distribution in massive elliptical galaxies encodes their evolutionary history, thus providing an avenue to constrain the baryonic astrophysics in their evolution. The power-law assumption for the radial mass profile in ellipticals has been sufficient to describe several observables to the noise level, including strong lensing and stellar…
MaNGA AGN dwarf galaxies (MAD) - I. A new sample of AGNs in dwarf galaxies with spatially-resolved spectroscopy
Domínguez Sánchez, H.; Mezcua, M.
The finding of active galactic nuclei (AGNs) in dwarf galaxies has important implications for galaxy evolution and supermassive black hole formation models. Yet, how AGNs in dwarf galaxies form is still debated, in part due to scant demographics. We use the MaNGA survey, comprising ~10 000 galaxies at z < 0.15, to identify AGN dwarf galaxies us…
The APOGEE value-added catalogue of Galactic globular cluster stars
Cohen, Roger E.; Brownstein, Joel R.; Majewski, Steven R. +17 more
We introduce the Sloan Digital Sky Survey (SDSS)/ Apache Point Observatory Galactic Evolution Experiment (APOGEE) value-added catalogue of Galactic globular cluster (GC) stars. The catalogue is the result of a critical search of the APOGEE Data Release 17 (DR17) catalogue for candidate members of all known Galactic GCs. Candidate members are assig…
Statistical analysis of the gravitational anomaly in Gaia wide binaries
Hernandez, X.; Aguayo-Ortiz, A.; Verteletskyi, V. +1 more
The exploration of the low acceleration a < a0 regime, where a0 = 1.2 × 10-10 m s-2 is the acceleration scale of MOND around which gravitational anomalies at galactic scale appear, has recently been extended to the much smaller mass and length scales of local wide binaries thanks to the availability o…
GA-NIFS: NIRSpec reveals evidence for non-circular motions and AGN feedback in GN20
Charlot, Stéphane; Parlanti, Eleonora; Carniani, Stefano +15 more
We present rest-frame optical data of the
The ALMA REBELS survey: obscured star formation in massive Lyman-break galaxies at z= 4-8 revealed by the IRX-β and M⋆ relations
Inami, H.; Bowler, R. A. A.; Cullen, F. +23 more
We investigate the degree of dust obscured star formation in 49 massive (log10(M⋆/M⊙) > 9) Lyman-break galaxies (LBGs) at z = 6.5-8 observed as part of the Atacama Large Millimeter/submillimeter Array (ALMA) Reionization Era Bright Emission Line Survey (REBELS) large program. By creating deep stacks of the photo…
The connection between mergers and AGN activity in simulated and observed massive galaxies
Kocevski, Dale D.; Somerville, Rachel S.; Ostriker, Jeremiah P. +9 more
We analyse a suite of 29 high-resolution zoom-in cosmological hydrodynamic simulations of massive galaxies with stellar masses $M_{\rm star} \gt 10^{10.9} \, \mathrm{M}_\odot$, with the goal of better understanding merger activity among active galactic nuclei (AGN), AGN activity in merging systems, SMBH growth during mergers, and the role of gas c…
Wide post-common envelope binaries containing ultramassive white dwarfs: evidence for efficient envelope ejection in massive asymptotic giant branch stars
Cargile, Phillip A.; Bieryla, Allyson; Latham, David W. +7 more
Post-common envelope binaries (PCEBs) containing a white dwarf (WD) and a main-sequence (MS) star can constrain the physics of common envelope evolution and calibrate binary evolution models. Most PCEBs studied to date have short orbital periods (Porb ≲ 1 d), implying relatively inefficient harnessing of binaries' orbital energy for env…
Modelling the spectra of the kilonova AT2017gfo - II. Beyond the photospheric epochs
Smartt, S. J.; Sim, S. A.; Gillanders, J. H. +2 more
Binary neutron star mergers are the first confirmed site of element nucleosynthesis by the rapid neutron-capture process (r-process). The kilonova AT2017gfo is the only electromagnetic counterpart of a neutron star merger spectroscopically observed. We analyse the entire spectral sequence of AT2017gfo (from merger to +10.4 d) and identify seven em…
Spatially resolved Kennicutt-Schmidt relation at z ≈ 7 and its connection with the interstellar medium properties
Carniani, Stefano; Vallini, Livia; Ferrara, Andrea +7 more
We exploit moderately resolved [O $\scriptstyle \rm III$], [C $\scriptstyle \rm II$] and dust continuum ALMA observations to derive the gas density (n), the gas-phase metallicity (Z), and the deviation from the Kennicutt-Schmidt (KS) relation (κs) on $\approx \, \rm sub-kpc$ scales in the interstellar medium (ISM) of five bright Lyman B…
