Galaxy Zoo: the fundamentally different co-evolution of supermassive black holes and their early- and late-type host galaxies

open access: yes, 2010
We use data from the Sloan Digital Sky Survey and visual classifications of morphology from the Galaxy Zoo project to study black hole growth in the nearby universe (z 1040 erg s–1 in early- and late-type galaxies is fundamentally different.

The Stellar Mass Functions of Early and Late-Type Galaxies in Groups at Intermediate Redshifts

open access: yes, 2009
We study the stellar mass functions of early and late-type galaxies in a galaxy group system at a redshift of z=0.37 in order to investigate mass assembly histories in a type of rarely explored galaxy systems at intermediate redshifts which are ...

The Extended Baryonic Tully–Fisher Relation for SDSS MaNGA Galaxies

open access: yesThe Astrophysical Journal
The baryonic Tully–Fisher relation (BTFR), a relationship between the rotational velocity and baryonic mass in spiral galaxies, probes the relative content of baryonic and total mass in galaxies and thus provides a good test of dark matter content in ...

Diverse reddening distributions in sight lines for type Ia supernovae

open access: yesAstronomy & Astrophysics
Context. Accurate cosmological constraints from type Ia supernovae (SNe) require sufficiently accurate corrections for host-galaxy extinction. Modelling these corrections is challenged by the problem of disentangling the SN’s intrinsic colours from host ...

Longitudinal and cross‐sectional perspectives on elementary school children's post‐error slowing in reading and arithmetic

open access: yesBritish Journal of Educational Psychology, EarlyView.
Abstract Background This study investigated the development of primary school children's error‐related adjustments in reading and arithmetic, both cross‐sectionally and longitudinally. Aims We aimed to uncover monitoring‐based cognitive control processes and often‐overlooked strategy use in academic tasks requiring a balancing of speed and accuracy ...

Star clusters in unperturbed spiral galaxies [PDF]

open access: yes, 2008
Stars do not form in isolation, they form in groups known as star clusters. Star clusters are seen in a wide range of galaxies and environments. Their presence reveals the history of the host galaxy and the processes of its star formation.

SDSS-IV MaNGA: Distinct Structural Growth and Star Formation in Low and High Surface Brightness Disks

open access: yesThe Astrophysical Journal Supplement Series
We analyze a clean sample of 1118 late-type, face-on galaxies without active galactic nucleus contamination from the MaNGA survey. Their photometric structures are quantified via two-component (bulge + disk) decompositions of deep g -band images from the

The nature of late-type spiral galaxies

open access: yesMonthly Notices of the Royal Astronomical Society, 2009
We analyse V-and H-band surface photometry of a sample of 18 Sb-Sd galaxies. Combining high-resolution Hubble Space Telescope (HST) images with ground-based near-infrared observations, we extract photometric profiles, which cover the whole disc and provide the highest possible resolution.

Story2Board: A Training‐Free Approach for Expressive Visual Storytelling

open access: yesComputer Graphics Forum, EarlyView.
Abstract We present Story2Board, a training‐free framework for expressive storyboard generation from natural language. Existing methods narrowly focus on subject identity, overlooking key aspects of visual storytelling such as spatial composition, background evolution, and narrative pacing.

Probing the star formation history of early-type galaxies in clusters [PDF]

open access: yes, 1998
In this thesis, we present a new photometric catalogue of the local Coma galaxy cluster in the Johnson U- and V- bands. We cover an area of 3360arcmin(^2) of sky, to a depth of V = 20mag in a 13 arcsec diameter aperture, and produce magnitudes for ~ 1400
