The host galaxies of 2003fg-like type Ia supernovae

Lluís Galbany, Chris Ashall, Jing Lu +19

SN~2003fg-like events are a peculiar type Ia supernova (SN~Ia) subtype characterized by broader light curves, higher near-infrared luminosities, and stronger carbon absorptions at…

ZTF SN Ia DR2 follow-up: early excess in Type Ia supernova light curves

Tomás E. Müller-Bravo, Kate Maguire, Alaa Alburai +15

There is broad consensus that Type Ia supernovae (SNe Ia) are the thermonuclear explosions of C/O white dwarfs (WDs) in binary systems, but their progenitors and explosion mechanis…

An analysis of the Type Ia SN 2024gy and a comparison of different host extinction estimation techniques

Jacco H. Terwel, Kate Maguire, Cillian O'Donnell +38

Type Ia supernovae (SNe Ia) are well-known standardisable candles, and are one of the main ways to measure the distance to their host galaxies. However, extinction due to interstel…

The local ultraviolet signature of Type Ia supernova environments from HST and MUSE

Lluís Galbany, Cullen Abelson, Alaa Alburai +17

The local environment of a Type Ia supernova (SN~Ia) traces the local stellar-population age (a statistical proxy for the progenitor age), star formation, dust, and chemical enrich…

ZTF SN Ia DR2 follow-up: Characterization of subluminous Type Ia supernovae in the ZTF DR2 full sample

Alaa Alburai, Lluís Galbany, Umut Burgaz +19

The Zwicky Transient Facility Data Release 2 (ZTF DR2) includes a total of 3,628 Type Ia supernovae (SNe~Ia), providing the largest and most complete sample of spectroscopically co…

The Type Ia Supernova 2021hem: A 2003fg-like Event in an Apparently Hostless Environment

Subhash Bose, M. D. Stritzinger, A. Malmgaard +25

We report observations of Type Ia SN 2021hem, located in an apparently hostless environment. With a peak absolute B-band magnitude of -19.96 mag, and a lack of secondary maximum in…

Rapid follow-up observations of infant supernovae with the Gran Telescopio Canarias

Lluís Galbany, Claudia P. Gutiérrez, Lara Piscarreta +21

The first few hours of a supernova (SN) contain significant information about the progenitor system. The most modern wide-field surveys that scan the sky repeatedly every few days…

ZTF SN Ia DR2: Properties of the low-mass host galaxies of Type Ia supernovae in a volume-limited sample

U. Burgaz, K. Maguire, G. Dimitriadis +25

In this study, we explore the characteristics of `low-mass' () and `intermediate-mass' () host galaxies o…

ZTF SN Ia DR2: The diversity and relative rates of the thermonuclear SN population

G. Dimitriadis, U. Burgaz, M. Deckers +28

The Zwicky Transient Facility SN Ia Data Release 2 (ZTF SN Ia DR2) contains more than 3,000 Type Ia supernovae (SNe Ia), providing the largest homogeneous low-redshift sample of SN…

ZTF SN Ia DR2: The spectral diversity of Type Ia supernovae in a volume-limited sample

U. Burgaz, K. Maguire, G. Dimitriadis +30

More than 3000 spectroscopically confirmed Type Ia supernovae (SNe Ia) are presented in the Zwicky Transient Facility SN Ia Data Release 2 (ZTF DR2). In this paper, we detail the s…

A proper motion catalogue for the Milky Way's nuclear stellar disc

B. Shahzamanian, R. Schoedel, F. Nogueras-Lara +5

We present the results of a large-scale proper motion study of the central ~36'x16' of the Milky Way, based on our high angular resolution GALACTICNUCLEUS survey (epoch 2015) combi…
