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…
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…
The formation and evolution of Andromeda IX
Hedieh Abdollahi, Atefeh Javadi, Mohammad Taghi Mirtorabi +7
Local Group (LG), the nearest and most complete galactic environment, provides valuable information on the formation and evolution of the Universe. Studying galaxies of different s…
The Isaac Newton Telescope Monitoring Survey of Local Group Dwarf Galaxies. VI. The Star Formation History and Dust Production in Andromeda IX
Hedieh Abdollahi, Atefeh Javadi, Mohammad Taghi Mirtorabi +9
We present a photometric study of the resolved stellar populations in And IX, the closest satellite to the M31, a metal-poor and low-mass dwarf spheroidal galaxy. We estimate a dis…
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…
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…
EMISSA -- Exploring Millimetre Indicators of Solar-Stellar Activity II. Towards a robust indicator of stellar activity
Atul Mohan, Sven Wedemeyer, Peter H. Hauschildt +2
An activity indicator, which can provide a robust quantitative mapping between the stellar activity and the physical properties of its atmosphere, is important in exploring the phy…
Tracing the role of AGB stars in the Galactic Fluorine budget
Maryam Saberi
The cosmic origin of fluorine is still under debate. Asymptotic giant branch (AGB) stars are among the few suggested candidates to efficiently synthesis F in our Galaxy, however th…
First detection of AlF line emission towards M-type AGB stars
M. Saberi, T. Khouri, L. Velilla-Prieto +3
The nucleosynthesis production of fluorine (F) is still a matter of debate. Asymptotic giant branch (AGB) stars are one of the main candidates for F production. However, their cont…
Reflections on the photodissociation of CO in circumstellar envelopes
Martin Groenewegen, Maryam Saberi
Carbon monoxide (CO) is the most abundant molecule after molecular hydrogen and is important for the chemistry in circumstellar envelopes around evolved stars. When modelling the s…
CO and HCN isotopologue ratios in the outflows of AGB stars
M. Saberi, H. Olofsson, W. H. T. Vlemmings +3
Isotopologue line intensity ratios of circumstellar molecules have been widely used to trace the photospheric elemental isotopic ratios of evolved stars. However, depending on the…
Photodissociation of CO in the outflow of evolved stars
Maryam Saberi, Wouter Vlemmings, Elvire De Beck
Ultraviolet (UV) photodissociation of CO controls the abundances and distribution of CO and its photodissociation products. This significantly influences the gas-phase chemistry in…
H12CN and H13CN excitation analysis in the circumstellar outflow of R Scl
M. Saberi, M. Maercker, E. De Beck +3
Abridged. The 12CO/13CO ratio in the circumstellar envelope (CSE) of asymptotic giant branch (AGB) stars has been extensively used as the tracer of the photospheric 12C/13C ratio.…
The UK Infrared Telescope M33 monitoring project. IV. Variable red giant stars across the galactic disc
Atefeh Javadi, Maryam Saberi, Jacco Th. van Loon +3
We have conducted a near-infrared monitoring campaign at the UK InfraRed Telescope (UKIRT), of the Local Group spiral galaxy M33 (Triangulum). The main aim was to identify stars in…
Probing the Local Bubble with Diffuse Interstellar Bands. II. The DIB properties in the Northern hemisphere
Amin Farhang, Habib G. Khosroshahi, Atefeh Javadi +9
We present a new high signal to noise ratio spectroscopic survey of the Northern hemisphere to probe the Local Bubble and its surroundings using the Å and Å Diffuse…
