Potential signature of a quadrupolar Hubble expansion in Pantheon+ supernovae

Jessica A. Cowell, Suhail Dhawan, Hayley J. Macpherson

The assumption of isotropy -- that the Universe looks the same in all directions on large scales -- is fundamental to the standard cosmological model. This model forms the building…

The prevalence and influence of circumstellar material around hydrogen-rich supernova progenitors

Rachel J. Bruch, Avishay Gal-Yam, Ofer Yaron +44

Narrow transient emission lines (flash-ionization features) in early supernova (SN) spectra trace the presence of circumstellar material (CSM) around the massive progenitor stars o…

A BayeSN Distance Ladder: from a consistent modelling of Type Ia supernovae from the optical to the near infrared

Suhail Dhawan, Stephen Thorp, Kaisey S. Mandel +4

The local distance ladder estimate of the Hubble constant () is important in cosmology, given the recent tension with the early universe inference. We estimate from the…

LensWatch: I. Resolved HST Observations and Constraints on the Strongly-Lensed Type Ia Supernova 2022qmx ("SN Zwicky")

J. D. R. Pierel, N. Arendse, S. Ertl +39

Supernovae (SNe) that have been multiply-imaged by gravitational lensing are rare and powerful probes for cosmology. Each detection is an opportunity to develop the critical tools…

Uncovering a population of gravitational lens galaxies with magnified standard candle SN Zwicky

Ariel Goobar, Joel Johansson, Steve Schulze +35

Detecting gravitationally lensed supernovae is among the biggest challenges in astronomy. It involves a combination of two very rare phenomena: catching the transient signal of a s…

Relative intrinsic scatter in hierarchical Type Ia supernova siblings analyses: Application to SNe 2021hpr, 1997bq & 2008fv in NGC 3147

Sam M. Ward, Stephen Thorp, Kaisey S. Mandel +22

We present Young Supernova Experiment photometry of SN 2021hpr, the third Type Ia supernova sibling to explode in the Cepheid calibrator galaxy, NGC 3147. Siblings are usef…

SN 2020jgb: A Peculiar Type Ia Supernova Triggered by a Helium-Shell Detonation in a Star-Forming Galaxy

Chang Liu, Adam A. Miller, Abigail Polin +25

The detonation of a thin () helium shell (He-shell) atop a white dwarf (WD) is a promising mechanism to explain normal…

The quadrupole in the local Hubble parameter: first constraints using Type Ia supernova data and forecasts for future surveys

Suhail Dhawan, Antonin Borderies, Hayley J. Macpherson +1

The cosmological principle asserts that the Universe looks spatially homogeneous and isotropic on sufficiently large scales. Given the fundamental implications of the cosmological…

Multi-messenger constraints on the Hubble constant through combination of gravitational waves, gamma-ray bursts and kilonovae from neutron star mergers

Mattia Bulla, Michael W. Coughlin, Suhail Dhawan +1

The simultaneous detection of gravitational waves and light from the binary neutron star merger GW170817 led to independent measurements of distance and redshift, providing a direc…

Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies

Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200

In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological…

The detection efficiency of type Ia supernovae from the Zwicky Transient Facility: Limits on the intrinsic rate of early flux excesses

M. R. Magee, C. Cuddy, K. Maguire +8

Samples of young type Ia supernovae have shown `early excess' emission in a few cases. Similar excesses are predicted by some explosion and progenitor scenarios and hence can provi…

Hubble constant and nuclear equation of state from kilonova spectro-photometric light curves

M. A. Pérez-García, L. Izzo, D. Barba +17

The merger of two compact objects of which at least one is a neutron star is signalled by transient electromagnetic emission in a kilonova (KN). This event is accompanied by gravit…

The Final Season Reimagined: 30 Tidal Disruption Events from the ZTF-I Survey

Erica Hammerstein, Sjoert van Velzen, Suvi Gezari +30

Tidal disruption events (TDEs) offer a unique way to study dormant black holes. While the number of observed TDEs has grown thanks to the emergence of wide-field surveys in the pas…
