The Isaac Newton Telescope monitoring survey of Local Group dwarf galaxies--V. The star formation history of Sagittarius dwarf irregular galaxy derived from long period variable stars
Tahere Parto, Shahrzad Dehghani, Atefeh Javadi +7
We conducted an optical monitoring survey of the Sagittarius dwarf irregular galaxy (SagDIG) during the period of June 2016 -- October 2017, using the 2.5-m Isaac Newton Telescope…
Spectral identification and classification of dusty stellar sources using spectroscopic and multiwavelength observations through machine learning
Sepideh Ghaziasgar, Amirhossein Masoudnezhad, Atefeh Javadi +3
We proposed a machine learning approach to identify and distinguish dusty stellar sources employing supervised and unsupervised methods and categorizing point sources, mainly evolv…
Star Formation History of Two Fields in the Halo of NGC5128
Sima T. Aghdam, Atefeh Javadi, Seyedazim Hashemi +5
NGC5128 galaxy is a giant elliptical galaxy located in the Centaurus group of galaxies at 3.8 Mpc. We aim to study the star formation history (SFH) of two different fields of the g…
The Astrophysical Distance Scale: V. A 2% Distance to the Local Group Spiral M33 via the JAGB Method, Tip of the Red Giant Branch, and Leavitt Law
Abigail J. Lee, Laurie Rousseau-Nepton, Wendy L. Freedman +6
The J-region asymptotic giant branch (JAGB) method is a new standard candle that is based on the stable intrinsic J-band magnitude of color-selected carbon stars, and has a precisi…
From evolved Long-Period-Variable stars to the evolution of M31
Maryam Torki, Mahdieh Navabi, Atefeh Javadi +3
One of the ways to understand the genesis and evolution of the universe is to know how galaxies have formed and evolved. In this regard, the study of star formation history (SFH) p…
Mass-loss rates of cool evolved stars in M33 galaxy
Atefeh Javadi, Jacco Th. van Loon
We have conducted a near-infrared monitoring campaign at the UK InfraRed Telescope (UKIRT), of the Local Group spiral galaxy M33 (Triangulum). In this paper, we present the dust an…
