Euclid: Quick Data Release (Q1) -- Secondary nuclei in early-type galaxies
M. Fabricius, R. Saglia, F. Balzer +165
Massive early-type galaxies (ETGs) are believed to form primarily through mergers of less massive progenitors, leaving behind numerous traces of violent formation histories, such a…
Euclid: The - relation as a function of redshift. I. The black hole in NGC 1272
R. Saglia, K. Mehrgan, S. de Nicola +148
Core ellipticals, massive early-type galaxies have an almost constant inner surface brightness profile. The size of the core region correlates with the mass of the finally merged b…
The MICADO first light imager for the ELT: off-axis performance of PSF reconstruction
Matteo Simioni, Daniel Jodlbauer, Carmelo Arcidiacono +14
The highest scientific return, for adaptive optics (AO) observations, is achieved with a reliable reconstruction of the PSF. This is especially true for MICADO@ELT. In this present…
Accuracy and precision of triaxial orbit models I: SMBH mass, stellar mass and dark-matter halo
B. Neureiter, S. de Nicola, J. Thomas +3
We investigate the accuracy and precision of triaxial dynamical orbit models by fitting two dimensional mock observations of a realistic N-body merger simulation resembling a massi…
The two phases of core formation -- orbital evolution in the centres of ellipticals with supermassive black hole binaries
Matteo Frigo, Thorsten Naab, Antti Rantala +4
The flat stellar density cores of massive elliptical galaxies form rapidly due to sinking supermassive black holes (SMBH) in gas-poor galaxy mergers. After the SMBHs form a bound b…
Spectropolarimetry and photometry of the early afterglow of the gamma-ray burst GRB191221B
D. A. H. Buckley, S. Bagnulo, R. J. Britto +27
We report on results of spectropolarimetry of the afterglow of the long gamma-ray burst GRB 191221B, obtained with SALT/RSS and VLT/FORS2, as well as photometry from two telescopes…
