Hedieh Abdollahi, Atefeh Javadi, Jacco Th. van Loon +6
We present a comprehensive catalog, in the Sloan and Harris filters, of long-period variable (LPV) stars in the spheroidal dwarf satellites of the Andromeda galaxy, based o…
The Isaac Newton Telescope Monitoring Survey of Local Group Dwarf Galaxies. VII. Long-Period Variable Stars in the Nearest Starburst Dwarf Galaxy, IC 10
Mahtab Gholami, Atefeh Javadi, Hamidreza Mahani +7
To identify long-period variable (LPV) stars in IC10 - the nearest starburst galaxy of the Local Group (LG) - we conducted an optical monitoring survey using the 2.5-m Isaac Newton…
Deciphering Galactic Halos: A Detailed Review of Star Formation in NGC 5128 (Cen A)
Mahdi Abdollahi, Sima Taefi Aghdam, Atefeh Javadi +6
NGC 5128 (Centaurus A), the closest giant elliptical galaxy outside the Local Group to the Milky Way, is one of the brightest extragalactic radio sources. It is distinguished by a…
Detection of the Long Period Variable Stars of And II Dwarf Satellite galaxy
Hedieh Abdollahi, Atefeh Javadi, Jacco Th. van Loon +5
We conducted an extensive study of the spheroidal dwarf satellite galaxies around the Andromeda galaxy to produce an extensive catalog of LPV stars. The optical monitoring project…
The Complex Star Formation History of the Halo of NGC 5128 (Cen A)
Sima Taefi Aghdam, Atefeh Javadi, Seyedazim Hashemi +6
NGC 5128 (Cen A) is the nearest giant elliptical galaxy and one of the brightest extragalactic radio sources in the sky, boasting a prominent dust lane and jets emanating from its…
