Supernovae Unite: Host-Galaxy Mass Measurements of Type Ia Supernovae and Their Impact on Cosmology
J. Lee, R. Camilleri, T. M. Davis +22
Current consensus suggests that Type Ia supernova (SN Ia) brightnesses post light-curve standardization correlate with their host-galaxy stellar masses, which must be accounted for…
The Enigmatic Type Icn Supernova 2024abvb Located ~22 kpc from Its Host Galaxy
J. Shi, K. Auchettl, W. B. Hoogendam +29
We report multiwavelength observations of the highly offset (~22.4 kpc) SN 2024abvb, the sixth Type Icn supernova to date. With a peak magnitude of Mr = -19.55 +/- 0.11 mag, it is…
OzDES Reverberation Mapping of Active Galactic Nuclei: Final Data Release, Black-Hole Mass Results, & Scaling Relations
H. McDougall, T. M. Davis, Z. Yu +53
Over the last decade, the Australian Dark Energy (OzDES) collaboration has used Reverberation Mapping to measure the masses of high redshift supermassive black holes. Here we prese…
OzDES Reverberation Mapping Program: CIV lags from six years of data
A. Penton, H. McDougall, T. M. Davis +52
We present 29 successfully recovered CIV time lags in Active Galactic Nuclei from the complete Dark Energy Survey Reverberation Mapping campaign. The AGN in this sample span a reds…
The Dark Energy Bedrock All-Sky Supernova Program: Motivation, Design, Implementation, and Preliminary Data Release
Nora F. Sherman, Maria Acevedo, Dillon Brout +20
Precise measurements of Type Ia supernovae (SNe Ia) at low redshifts () serve as one of the most viable keys to unlocking our understanding of cosmic expansion, isotropy, and gr…
[O II] as an Effective Indicator of the Dependence Between the Standardised Luminosities of Type Ia Supernovae and the Properties of their Host Galaxies
B. Martin, C. Lidman, D. Brout +3
We have obtained IFU spectra of 75 SN Ia host galaxies from the Foundation Supernova survey to search for correlations between the properties of individual galaxies and SN Hubble r…
Calibrating the Absolute Magnitude of Type Ia Supernovae in Nearby Galaxies using [OII] and Implications for
M. Dixon, J. Mould, C. Lidman +69
The present state of cosmology is facing a crisis where there is a fundamental disagreement in measurements of the Hubble constant (), with significant tension between the e…
Modelling the impact of host galaxy dust on type Ia supernova distance measurements
B. Popovic, P. Wiseman, M. Sullivan +65
Type Ia Supernovae (SNe Ia) are a critical tool in measuring the accelerating expansion of the universe. Recent efforts to improve these standard candles have focused on incorporat…
The Dark Energy Survey Supernova Program: An updated measurement of the Hubble constant using the Inverse Distance Ladder
R. Camilleri, T. M. Davis, S. R. Hinton +77
We measure the current expansion rate of the Universe, Hubble's constant , by calibrating the absolute magnitudes of supernovae to distances measured by Baryon Acoustic Oscill…
The Dark Energy Survey Supernova Program: Light curves and 5-Year data release
B. O. Sánchez, D. Brout, M. Vincenzi +82
We present photometric light curves for the full 5 years of the Dark Energy Survey Supernova program (DES-SN), obtained with both forced Point Spread Function (PSF) photomet…
The Dark Energy Survey Supernova Program: Slow supernovae show cosmological time dilation out to
R. M. T. White, T. M. Davis, G. F. Lewis +67
We present a precise measurement of cosmological time dilation using the light curves of 1504 type Ia supernovae from the Dark Energy Survey spanning a redshift range $0.1\lesssim…
OzDES Reverberation Mapping Program: Stacking analysis with H, Mg II and C IV
Umang Malik, Rob Sharp, A. Penton +47
Reverberation mapping is the leading technique used to measure direct black hole masses outside of the local Universe. Additionally, reverberation measurements calibrate secondary…
DES Science Portal: Computing Photometric Redshifts
Julia Gschwend, Aurelio Carnero Rosell, Ricardo Ogando +68
A significant challenge facing photometric surveys for cosmological purposes is the need to produce reliable redshift estimates. The estimation of photometric redshifts (photo-zs)…
