Toward the Italian Astronomical Community's Contribution to HWO: Science, Technology, and Instrument Concepts
A. Fontana, F. Annibali, N. Antonietti +101
This paper summarizes the interest of the Italian astronomical community in the possible participation in the development of the Habitable Worlds Observatory (HWO). It is largely b…
The transitional Type Ibn/IIn SN 2022pda, with pre-explosion outbursts and a double-peaked light curve
Y. -Z. Cai, A. Pastorello, R. Chiba +65
We report the results of a photometric and spectroscopic follow-up campaign of the unusual interacting supernova (SN) 2022pda. Precursor variability lasting days is obse…
ESO Expanding Horizons: Underluminous Thermonuclear Supernovae
Paul J. Groot, Simone Scaringi, Nancy Elias-Rosa
Underluminous Thermonuclear Supernovae (uTSNe) are an emerging class of transient events that resemble classic Supernovae Type Ia, but peak at much lower luminosities. Suspected to…
Discovery and characterization of ZTF J0112+5827: An 80.9-minute polar with strong cyclotron features
Jiamao Lin, Liangliang Ren, Chengyuan Li +9
We report the discovery and characterization of ZTF J0112+5827, a new magnetic cataclysmic variable with an orbital period of 80.9 minutes. ROSAT observations revealed X-ray emissi…
JWST NIRSpec+MIRI Observations of the nearby Type IIP supernova 2022acko
M. Shahbandeh, C. Ashall, P. Hoeflich +65
We present JWST spectral and photometric observations of the Type IIP supernova (SN) 2022acko at ~50 days past explosion. These data are the first JWST spectral observations of a c…
The orbital period of the recurrent nova V2487 Oph revealed
Pablo Rodríguez-Gil, Jesús M. Corral-Santana, Nancy Elías-Rosa +3
We present the first reliable determination of the orbital period of the recurrent nova V2487 Oph (Nova Oph 1998). We derived a value of d ( h) from…
SNe 2013K and 2013am: observed and physical properties of two slow, normal Type IIP events
L. Tomasella, E. Cappellaro, M. L. Pumo +28
We present one year of optical and near-infrared photometry and spectroscopy of the Type IIP SNe 2013K and 2013am. Both objects are affected by significant extinction, due to their…
Gaia17biu/SN 2017egm in NGC 3191: The closest hydrogen-poor superluminous supernova to date is in a "normal", massive, metal-rich spiral galaxy
Subhash Bose, Subo Dong, A. Pastorello +55
Hydrogen-poor superluminous supernovae (SLSNe-I) have been predominantly found in low-metallicity, star-forming dwarf galaxies. Here we identify Gaia17biu/SN 2017egm as an SLSN-I o…
Gaia16apd -- a link between fast-and slowly-declining type I superluminous supernovae
T. Kangas, N. Blagorodnova, S. Mattila +18
We present ultraviolet, optical and infrared photometry and optical spectroscopy of the type Ic superluminous supernova (SLSN) Gaia16apd (= SN 2016eay), covering its evolution from…
Gamma-Ray emission from SN2014J near maximum optical light
J. Isern, P. Jean, E. Bravo +17
The optical light curve of Type Ia supernovae (SNIa) is powered by thermalized gamma-rays produced by the decay of 56Ni and 56Co, the main radioactive isotopes synthesized by the t…
LSQ14bdq: A Type Ic super-luminous supernova with a double-peaked light curve
M. Nicholl, S. J. Smartt, A. Jerkstrand +28
We present data for LSQ14bdq, a hydrogen-poor super-luminous supernova (SLSN) discovered by the La Silla QUEST survey and classified by the Public ESO Spectroscopic Survey of Trans…
OGLE-2013-SN-079: a lonely supernova consistent with a helium shell detonation
C. Inserra, S. A. Sim, L. Wyrzykowski +31
We present observational data for a peculiar supernova discovered by the OGLE-IV survey and followed by the Public ESO Spectroscopic Survey for Transient Objects. The inferred reds…
