Galaxy-SMBH co-evolution in 2,435 DESI disk galaxies and merger-free BH growth in bulgeless disks

Sophie M. Jewell, Rebecca J. Smethurst, Chris J. Lintott +8

We analyse black hole scaling relations for disk-dominated galaxies, and present evidence for secularly driven galaxy-black hole co-evolution. We do this observationally by looking…

Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory

Courtney D. Dressing, Danica Adams, Evelyne Alecian +324

The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…

Investigating the need for a robust ultraviolet filter set aboard the Habitable Worlds Observatory

Kyle Cook, Benne Holwerda, Clayton Robertson

High resolution, ultraviolet imaging is often unavailable across the sky, even in heavily studied fields such as the Chandra Deep Field - South. The Habitable Worlds Observatory is…

Looking At the Distant Universe with the MeerKAT Array: the HI Mass Function in the Local Universe

Amir Kazemi-Moridani, Andrew J. Baker, Marc Verheijen +24

We present measurements of the neutral atomic hydrogen (HI) mass function (HIMF) and cosmic HI density () at from the Looking at the Distant Unive…

A multiwavelength overview of the giant spiral UGC 2885

Matheus C. Carvalho, Bavithra Naguleswaran, Pauline Barmby +4

UGC 2885 (z = 0.01935) is one of the largest and most massive galaxies in the local Universe, yet its undisturbed spiral structure is unexpected for such an object and unpredicted…

Detection and characterization of M-L-T-Y dwarfs belonging to the Milky Way Disks and Stellar Halo with the Roman Space Telescope

Benne Holwerda, Nor Pirzkal, Adam Burgasser +1

How many low-mass stars, brown dwarfs and free-floating planets are in the Milky Way? And how are they distributed in our Galaxy? Recent studies of Milky Way interlopers in high-re…

Is NGC 300 a pure exponential disk galaxy?

In Sung Jang, Roelof S. de Jong, I. Minchev +6

NGC 300 is a low-mass disk galaxy in the Sculptor group. In the literature, it has been identified as a pure exponential disk galaxy, as its luminosity profile could be well fitted…

Galaxy classification: A machine learning analysis of GAMA catalogue data

Aleke Nolte, Lingyu Wang, Maciej Bilicki +2

We present a machine learning analysis of five labelled galaxy catalogues from the Galaxy And Mass Assembly (GAMA): The SersicCatVIKING and SersicCatUKIDSS catalogues containing mo…

What can the occult do for you?

B. W. Holwerda, W. C. Keel

Interstellar dust is still a dominant uncertainty in Astronomy, limiting precision in e.g., cosmological distance estimates and models of how light is re-processed within a galaxy.…

Milky Way Red Dwarfs in the BoRG Survey; Galactic scale-height and the distribution of dwarfs stars in WFC3 imaging

B. W. Holwerda, M. Trenti, W. Clarkson +10

We present a tally of Milky Way late-type dwarf stars in 68 WFC3 pure-parallel fields (227 arcmin^2) from the Brightest of Reionizing Galaxies (BoRG) survey for high-redshift galax…

Quantified HI Morphology IV: The Merger Fraction and Rate in WHISP

B. W. Holwerda, N. Pirzkal, W. J. G. de Blok +3

The morphology of the atomic hydrogen (HI) disk of a spiral galaxy is the first component to be disturbed by a gravitational interaction such as a merger between two galaxies. We u…

Quantified HI Morphology II : Lopsidedness and Interaction in WHISP Column Density Maps

B. W. Holwerda, N. Pirzkal, W. J. G. de Blok +4

Lopsidedness of the gaseous disk of spiral galaxies is a common phenomenon in disk morphology, profile and kinematics. Simultaneously, the asymmetry of a galaxy's stellar disk, in…

Quantified HI Morphology I: Multi-Wavelengths Analysis of the THINGS Galaxies

B. W. Holwerda, N. Pirzkal, W. J. G. de Blok +4

Galaxy evolution is driven to a large extent by interactions and mergers with other galaxies and the gas in galaxies is extremely sensitive to the interactions. One method to measu…

Trumpeting the Vuvuzela: UltraDeep HI observations with MeerKAT

B. W. Holwerda, S-L. Blyth

The MeerKAT UltraDeep HI Survey aims to observe the 21 cm emission line of neutral hydrogen gas out to a redshift of z=1 and beyond. From both direct detections and stacked signal,…

The onset of warps in Spitzer observations of edge-on spiral galaxies

Kanak Saha, Roelof de Jong, Benne Holwerda

We analyze warps in the nearby edge-on spiral galaxies observed in the {\em Spitzer/IRAC} 4.5 micron band. In our sample of 24 galaxies we find evidence of warp in 14 galaxies. We…
