Impact of Spacecraft Orbit Uncertainties and Velocity Mismodeling on the LISA Gravitational-Wave Response
Lorenzo Speri, Olaf Hartwig, Waldemar Martens +5
The Laser Interferometer Space Antenna (LISA) is a space-based gravitational wave observatory that consists of three spacecraft in a near-equilateral triangular formation. The spac…
LISA and the LISA Science Team
Anna Heffernan, Chiara Caprini, Neil Cornish +19
LISA, the Laser Interferometer Space Antenna, due to launch mid-2035, is a large class space mission by the European Space Agency (ESA). In partnership with NASA and ESA-member sta…
WIggle Corrector Kit for NIRSpEc Data: WICKED
Antoine Dumont, Nadine Neumayer, Anil C. Seth +8
The point-spread function of the integral-field unit (IFU) mode of the JWST's NIRSpec is heavily under-sampled, creating resampling noise seen as low-frequency sinusoidal-like arti…
Growing a nuclear star cluster from star formation and cluster mergers: The JWST NIRSpec view of NGC 4654
Katja Fahrion, Torsten Böker, Michele Perna +10
We present a detailed study of the centre of NGC4654, a Milky Way-like spiral galaxy in the Virgo cluster that has been reported to host a double stellar nucleus, thus promising a…
LISA Definition Study Report
Monica Colpi, Karsten Danzmann, Martin Hewitson +108
The Laser Interferometer Space Antenna (LISA) is the first scientific endeavour to detect and study gravitational waves from space. LISA will survey the sky for Gravitational Waves…
GA-NIFS: Early-stage feedback in a heavily obscured AGN at
Eleonora Parlanti, Stefano Carniani, Hannah Übler +19
Dust-obscured galaxies are thought to represent an early evolutionary phase of massive galaxies in which the active galactic nucleus (AGN) is still deeply buried in significant amo…
Overview of the JWST Advanced Deep Extragalactic Survey (JADES)
Daniel J. Eisenstein, Chris Willott, Stacey Alberts +75
We present an overview of the James Webb Space Telescope (JWST) Advanced Deep Extragalactic Survey (JADES), an ambitious program of infrared imaging and spectroscopy in the GOODS-S…
GA-NIFS: Black hole and host galaxy properties of two z6.8 quasars from the NIRSpec IFU
Madeline A. Marshall, Michele Perna, Chris J. Willott +20
Integral Field Spectroscopy (IFS) with JWST NIRSpec will significantly improve our understanding of the first quasars, by providing spatially resolved, infrared spectroscopic capab…
The Near-Infrared Spectrograph (NIRSpec) on the James Webb Space Telescope III. Integral-field spectroscopy
T. Böker, S. Arribas, N. Lützgendorf +28
The Near-Infrared Spectrograph (NIRSpec) on the James Webb Space Telescope (JWST) offers the first opportunity to use integral-field spectroscopy from space at near-infrared wavele…
Asymmetric spatial distribution of sub-solar metallicity stars in the Milky Way nuclear star cluster
A. Feldmeier-Krause, W. Kerzendorf, T. Do +10
We present stellar metallicity measurements of more than 600 late-type stars in the central 10 pc of the Galactic centre. Together with our previously published KMOS data, this dat…
Formation Mechanisms of IMBH in Globular Clusters
Mirek Giersz, Nathan Leigh, Arkadiusz Hypki +2
We very briefly discuss proposed in the literature possible scenarios for intermediate mass black holes (IMBH) formation in globular clusters. We also discuss the results of the MO…
Masses and Scaling Relations for Nuclear Star Clusters, and their Coexistence with Central Black Holes
Iskren Y. Georgiev, Torsten Böker, Natan Leigh +2
Galactic nuclei typically host either a Nuclear Star Cluster (NSC, prevalent in galaxies with masses ) or a Massive Black Hole (MBH, common in galaxies wit…
Stellar winds near massive black holes: The case of the S-stars
Nora Lützgendorf, Edwin van der Helm, Inti Pelupessy +1
The Galactic center provides a unique laboratory to study the interaction of a supermassive black hole (SMBH) with its gaseous and stellar environment. Simulations to determine the…
Intermediate-mass black holes in globular clusters: observations and simulations
Nora Lützgendorf, Markus Kissler-Patig, Karl Gebhardt +9
The study of intermediate-mass black holes (IMBHs) is a young and promising field of research. Formed by runaway collisions of massive stars in young and dense stellar clusters, in…
On the coexistence of stellar-mass and intermediate-mass black holes in globular clusters
Nathan W. C. Leigh, Nora Luetzgendorf, Aaron M. Geller +3
In this paper, we address the question: What is the probability of stellar-mass black hole (BH) binaries co-existing in a globular cluster with an intermediate-mass black hole (IMB…
Large scale kinematics and dynamical modelling of the Milky Way nuclear star cluster
A. Feldmeier, N. Neumayer, A. Seth +6
Within the central 10pc of our Galaxy lies a dense nuclear star cluster (NSC), and similar NSCs are found in most nearby galaxies. Studying the structure and kinematics of NSCs rev…
N-body simulations of globular clusters in tidal fields: Effects of intermediate-mass black holes
Nora Lützgendorf, Holger Baumgardt, J. M. Diederik Kruijssen
Intermediate-mass black holes (IMBHs) may provide the missing link to understanding the growth of supermassive black holes in the early Universe. Some formation scenarios predict t…
