Compressing radio interferometric visibility data into a probabilistic model using sparse Gaussian processes
Takafumi Tsukui
Next-generation radio interferometers will produce massive data volumes, making it impractical to store original visibility measurements and later combine observations in spat…
Enhanced rates of stellar radial migration in gas-rich discs at high redshift
HanYuan Zhang, Thor Tepper-GarcÃa, Vasily Belokurov +6
Radial migration and dynamical heating redistribute stars within galactic discs and thereby modify the chemo-kinematic structure of their host galaxies. Usually, these secular proc…
Formation of Substructure in Luminous Submillimeter Galaxies (FOSSILS): Evidence of Multiple Pathways to Trigger Starbursts in Luminous Submillimeter Galaxies
Ryota Ikeda, Daisuke Iono, Ken-ichi Tadaki +19
We present an analysis of rest-frame optical and far-infrared continuum emission in three luminous submillimeter galaxies (SMGs) at . The SMGs are spatial…
Turbulent gas-rich discs at high redshift: origin of thick stellar discs through 3D 'baryon sloshing'
Joss Bland-Hawthorn, Thor Tepper-Garcia, Oscar Agertz +8
In response to recent observations from JWST and ALMA, we explore a new class of dynamically self-consistent models using our AGAMA/Ramses hydrodynamic N-body framework (Nexus) tha…
Spatially non-parametric recovery of intrinsic kinematic maps in pre- to post-merger galaxies
Isaac Kanowski, Emily Wisnioski, J. Trevor Mendel +2
We introduce an adaptable kinematic modelling tool called ROHSA-SNAPD, "Spatially Non-parametric Approach to PSF Deconvolution using ROHSA". ROHSA-SNAPD utilises kinematic regulari…
Evolution of Gas Velocity Dispersion in Discs from to
E. Wisnioski, J. T. Mendel, R. Leaman +3
Together optical/near infrared integral field spectroscopy and resolved sub-millimetre interferometry data have mapped the ionised and molecular gas motions in nearly one thousand…
