Autor: T Jayasinghe, Todd A Thompson, C S Kochanek, K Z Stanek, D M Rowan, D V Martin, Kareem El-Badry, P J Vallely, J T Hinkle, D Huber, H Isaacson, J Tayar, K Auchettl, I Ilyin, A W Howard, C Badenes

We report the discovery of a stripped giant + lower giant binary, 2M04123153+6738486 (2M0412), identified during a search for non-interacting compact object-star binaries. 2M0412 is an evolved ($T_{\rm eff, giant}\simeq4000$ K), luminous ($L_{\rm gia

Objectives We assessed the prevalence of potentially inappropriate medication (PIM) among older (≥ 65 years) people living with HIV (O-PLWH) in the region of Madrid. Methods We analysed the dispensation registry of community and hospital pharmacies

No hot and luminous progenitor for Tycho’s supernova

Autor: Marat Gilfanov, Tyrone E. Woods, C. Badenes, Parviz Ghavamian

Publikováno v: Nature Astronomy. 1:800-804

Type Ia supernovae have proven vital to our understanding of cosmology, both as standard candles and for their role in galactic chemical evolution; however, their origin remains uncertain. The canonical accretion model implies a hot and luminous prog

The Exceptional X-ray Evolution of SN1996cr in High Resolution

Autor: C. Badenes, Franz E. Bauer, J. Quirola-Vasquez, T. Nymark, Dom Walton, Vikram V. Dwarkadas, W. N. Brandt

Publikováno v: Mon Not R Astron Soc

We present X-ray spectra spanning 18 years of evolution for SN\,1996cr, one of the five nearest SNe detected in the modern era. {\it Chandra} HETG exposures in 2000, 2004, and 2009 allow us to resolve spectrally the velocity profiles of Ne, Mg, Si, S

CO observations allow estimations of the gas content of molecular clouds, which trace the reservoir of cold gas fuelling star formation, as well as to determine extinction via H$_2$ column density, N(H$_2$). Here, we studied millimetric and optical p

Balmer-Dominated Shocks Exclude Hot Progenitors for Many Type Ia Supernovae

Autor: Marat Gilfanov, Parviz Ghavamian, C. Badenes, Tyrone E. Woods

The evolutionary mechanism underlying Type Ia supernova explosions remains unknown. Recent efforts to constrain progenitor models based on the influence that their high energy emission would have on the interstellar medium (ISM) of galaxies have prov

X-ray studies of supernova remnants: A different view of supernova explosions

Autor: C. Badenes

Publikováno v: Proceedings of the National Academy of Sciences. 107:7141-7146

The unprecedented spatial and spectral resolutions of Chandra have revolutionized our view of the X-ray emission from supernova remnants. The excellent data sets accumulated on young, ejecta dominated objects like Cas A or Tycho present a unique oppo

The metallicity of a supernova progenitor, together with its mass, is one of the main parameters that can rule the progenitor's fate. We present the second study of nearby supernova (SN) host galaxies (0.005 10 dex) by targeted searches. We neither f

A double white dwarf with a paradoxical origin?

Autor: N. Prasert, D. Koester, J. J. Hermes, Avishay Gal-Yam, S. Kengkriangkrai, Madelon C. P. Bours, S. E. Thompson, Boris T. Gänsicke, Alina G. Istrate, M. Kilic, C. Badenes, John R. Thorstensen, Thomas M. Tauris, V. S. Dhillon, T. R. Marsh, F. Mullally, D. Steeghs

We present Hubble Space Telescope UV spectra of the 4.6 h period double white dwarf SDSS J125733.63+542850.5. Combined with Sloan Digital Sky Survey optical data, these reveal that the massive white dwarf (secondary) has an effective temperature T2 =
